[About Samsung Chromebook Plus's performance and external ports]

In general, Chromebook performance depends on the Octane Score-Javascript benchmark measurement

My Chromebook Plus's Octane Score was 9480.

For reference, the Score for my Asus Chromebook Flip 10.2 was 4805.

However, this is only a small reference, but it does not seem to measure the performance of the entire Chromebook.

For example, if you call it minus one degree in winter weather forecast, sometimes the actual temperature you feel can be at minus 5 degrees. The Chromebook also seems to have the speed that it actually feels. In other words, depending on the usage pattern of the user and the main tasks, the speed of perception may be slow or may be fast.

As I can see from the fact that this device has one of ARM CPU series, it is obvious that such a device that responds with a click is indispensable.

However, for most common business tasks (G Suite cloud-based), it seems to be very graceful and seem to be responding moderately (not the fastest response, but the normal response, not the burdensome rack).

In addition, Android apps have outperformed their normal behavior beyond what we expected. (Probably one of the benefits of ARM chips). Of course, in my personal work patterns, I rarely use Android apps on this Chromebook.

As you can guess, Chrome OS installed on this Samsung Chromebook Plus seems to have made a lot of optimizations in cooperation with Google. In particular, it looks more like supporting stylus pens that are not yet supported on other Chromebooks, and Google Keep memos being the default app for Samsung stylus pens.

For reference, I am using Google Docs, spreadsheet for G Suite, Google presentation for presentation slides, and occasional survey form for all document work. Of course, I am working on sending and receiving mail to Gmail.

Screenshots and annotations on Chrome are using the Awesome Screenshot as an extension for Google Chrome, and screen-recording and video creation can be done using 'Screencastify' to upload screen-recorded results to YouTube and to create animated GIF images .

The external connection ports of Samsung Chromebook Plus are all two USB Type C ports.

USB memory, HDMI or RGB VGA connection for dual monitor connection, ethernet connection etc. requires gender or a separate adapter.

At the time Apple released the new MacBook, it offered only a USB Type C port, which caused many complaints from users (Apple sells a separate gender or adapter at an extra cost) How glad is it to have one port on each side?

I have a gender (Micro USB 5-pin charger-to-USBC conversion gender) that was already using the Google Nexus 6P smartphone (this smartphone already offers fast charging to the USBC port). However, I purchased an adapter (HDMI port 1, USB 3.0 port 1, USBC charging port 1) for an HDMI dual monitor connection.

If you connect this monitor to the left USBC port of your Samsung Chromebook after purchasing this multiport for external monitor connection, the monitor screen periodically jiggles (as if the power is weak and the screen shakes) I can not confirm the problem with the purchased MULTI port adapter, but when I connect it to the right USBC terminal on the Chromebook (above picture), it works well without any problem. Therefore, the adapter is connected to the right side for monitor connection and the left side for other USB hub connection (see photo above).

The benefit of the USBC port is fast charging, high transfer speed (double speed of USB 3.0), and no connection at all. Most of the devices coming out in the coming years (Apple MacBook, Chromebook, Google smartphone pixel) are expected to be USBC.

Here are some of the complaints of Samsung Chromebook Plus devices .

First, the keyboard is smaller than the standard keyboard size. In particular, backspace key and tab key are smaller than standard keyboards. It is more inconvenient than I thought because I often write a lot of documents and often press backspace. It can be used to become accustomed.

Second, the touch of the keyboard is not so good. You have to get some strength when you press it. And every time I press a keyboard, I feel like I press a little low-cost keyboard.

Third, the touch sensitivity of the touch pad is not good. It is not particularly inconvenient to use, but it needs to be improved.

Fourth, the problem seems to be due to the MS rather than the problem of Samsung Chromebook. In the first half of 2016, Google announced its first Google Play Store support for Chrome OS, and announced that all Android apps will be able to run on Chrome OS. At the time, it was able to install Android apps on three Chromebooks (Google Chromebook Pixel (2015), Asus Chromebook Flip 10.2, and Acer R13 Convertible). At that time, after purchasing the Asus Chromebook Flip 10.2, I installed the free MS Office apps for Android and used them well, and from the moment it could not install these office apps on Chromebooks. At present, it can be installed on only smartphone for Android, but it can not be installed on Samsung Chromebook which supports Android app.

[A Case study of Samsung Chromebook Plus's Display]

There was some conflict between the Asus C302CA and Samsung Chromebook Plus models for this Chromebook purchase. In the end, however, Chromebook Plus made the final decision.

  The purchase motive of Samsung Chromebook Plus is simple. If most of the Chromebooks I used (Acer C720p, Asus Flip 10.2) were serving as a second computer that consumes content at home (such as searching the web, watching videos, or occasionally watching netflix movies, etc.) It is a tool for creating content that is not intended for 2nd computer consuming but also for testing the possibility of being used as a main computer for business use.


Earlier, I had already tasted the touchscreen with the Asus Chromebook Flip 10.2 model, 360 degrees of screen rotation, installing the Google Play Store Android app on Chrome OS, and so on.

This Samsung Chromebook has a 3: 2 aspect ratio, which is the same rate as the earlier Pixel Chromebooks from Google.

Given that Google's proprietary Chromebook pixels were in a 3: 2 ratio, the Samsung Chromebook Plus will be a fountain of a second Chromebook with a 3: 2 ratio.

While most other Chromebooks are in the 16: 9 ratio, there is a reason why Samsung has released a 3: 2 ratio.

My personal opinion is that it is designed to be suitable for content creation (mainly companies with a lot of paperwork) so that companies can use it as a main computer, rather than a device for content consumption for 2nd computer.

The screenshot below compares the same Google document with the 16: 9 ratio of Chromebooks and 3: 2 ratio of Samsung Chromebooks.

  Acer C720p Chromebook 


Asus Flip 10.2 Chromebook

Samsung Chromebook Plus
As you can see in the screenshot above, you can see that the 3: 2 ratio screen shows a range of documents larger than 16: 9.

Samsung Chromebook Plus resolution vs. Google Chromebook Pixel (2015) resolution 12.3 "LED Display (2400 x 1600) 3: 2 aspect ratio

Chromebook Pixel (2015): 12.85-inch touchscreen, 2560 x 1700 resolution, 3: 2 aspect ratio

The clarity of the screen is the clearest of the Chromebooks we've used so far.

[TIP: How to query in Natural Language (NLP) within Google Spreadsheets]

Introduced in the Google Cloud Next 2017, this feature allows you to Question/Answer in natural language within Google Spreadsheet.

In general, spreadsheet novices often do not know how to use a sheet or the functions Spreadsheet provide, so even if there is useful data in the sheet, it is often misaligned because of poor analysis.

If you take advantage of the Explore function in 'Spreadsheet' as shown below, you can create a good report.

This is a sample statement that can be queried in the Explore of a sheet.

1. What were the top item on 2017
2. How many unique countries
3. What percentage of Represent is '이영희'
5. Who is the top represent?
6. Top Sold Units for Rep of '홍길동'
7. How many sold items by '홍길동

[What is Team Drive?] for G Suite Business and G Suite for Education (White Paper)

Finaly. Google announced Team Drives officially for G Suite Business and G Suite for Education at Next 2017. Here is the more detail information on what the Team Drive is and how to use.

Team Drive  White Paper
What is Team Drive?
G Suite Business/G Suite for Education


G Suite Business (Unlimited) and G Suite for Education is a new addition to Google Drive. It's a new addition to complement the functionality you need to team-collaborate on your existing Google Drive.
Note: This white paper was completed in December 2016. I have been selected as a beta tester by Google's Early Adopter Program and are based on tests that are only allowed on a domain. It is currently in beta. Google's full release is scheduled for early 2017. The information below is subject to change in the official release version

Constraints on Google Drive  
  • If the owner of the document or files in the shared folder retires and the administrator deletes the account, all files and documents created by the retiree will be deleted.
  • If you've shared Drive folders with Google Groups, you can add new members to Groups. You will need to reshare these new members with the Drive folders or documents that were previously shared with the group.
    • The marketing department manager creates a Marketing folder within Google Drive and shares the folder with the Google groups - If you currently have 5 members in the group, the Marketing folder will be shared to 5 people. In the future, new employee, Charly, joins the marketing department. It is added as a member to the all the materials previously shared with should be shared to Charly. However, the Marketing folder in Google Drive is not automatically shown on Charly’s Google Drive.  The marketing department manager can resubmit the owner of the Marketing folder to Charly.
    • There are restrictions on centralized control or team specific drive management functions.
    • In Google Drive, all files are managed by the owner created by the individual account. This means that you can not have full ownership of shared folders and all files stored in folders.
    • Each individual owns ownership of documents or files created with individual accounts. Files with different ownership can coexist within a shared folder. This makes it difficult to manage the files of each owner.
      • If file owners intentionally delete files or move them to another folder, the files will not be visible in other people's folders they share.
    • It is difficult to build a form like a centralized controllable file server for a company-wide or team-specific, department-specific.
    • After you create a Team Shared Folder, you can not give team members rights to create folders in subfolders and prevent them from being deleted or moved.
    • The administrator does not have a way to modify the share permissions of the folders users create. (Sharing permissions can only be changed by the folder owner)

What is Team Drive?

Team Drive is a shared space that allows you to collaborate with your team. This is a new service to complement the functionality you need for team collaboration in your existing Google Drive.

Team drives, like existing Google Drive, can use team drives for all users with G Suite Business (Unlimited) and G Suite for Education accounts.

Administrators can block users from creating new team drives by January 1, 2018, and from then on, all users will be able to create team drives.

With Team Drive, you can freely create and share folders and subfolders just like Google Drive does. However, there is a new rule for sharing as below.
