Just installed and tried it; the idea behind is indeed fascinating but it has some utterly detrimental inconveniences.
When importing bookmarks, the way and the order of their display is completely screwed. Not only that it misses that little arrow on the right if you have too many bookmarks, but you can't even change their orders in the Bookmarks menu. It's unacceptable.
It also fails to load Gmail, referring to some cookie error, but the issue persists whether I allow cookies or not.
I can't integrate it full to my use under these circumstances.
I think it's way too early for mass adoption. The fact that it doesn't crash at this stage is a huge plus, IMHO. Give it some - more - time.
Yeah I also think I should.
