Here is a preview of the “unstable” version ( quite stable actually but Google has a sense of humour that I am using on my Ubuntu Linux
1) Noticeably faster browsing. I mean faster browsing and loading of images.
2) Still some trouble with Adobe plugins and Facebook games
3) Cool customized themes (see below)
4) Note the time IN THE BROWSER
5) Quite easy and stable to use with the most visited sites and the default search with suggestions within address bar
