Why Google Chromebook doesn't much attract?

I am using the catch website which can keep personal memos and notes. Mostly, I am using this app from Android phone.

And I just thought that this app might have Chrome browser's app so I can make notes without internet connection, I thought.

This is a screen shot of catch app in Google Chrome's webstore.

What this app does is just open the website of catch. Nothing more.

So this is an app or just a bookmark?

I know some people might need bookmark as app but if Chromebook can't use with internet connection, how can you sell the product to the country with not-so-good internet connection and people who living in outside city-I don't think most country has very good internet infrastructure in countryside.

Oh, I forgot to mention that not only catch app did this.

I have seen a number of apps did this, too. And even google apps.

Anyway, that's why I wrote review with this comment:

Nowadays, bookmark became app. How clever!
