I thought it was very quick, but it's not particulary innovative. FF and Safari have been using tabs for years, as does pretty much every browser out there nowadays. And the "homepage" of website thumbnails based on your browsing history is a feature that Opera packed into their 9.5 release before GC came out, and I think Opera is a nicer browser anyway - it has some great feautres, including thumbnail previews of current web pages when you hover over the tab....

I like the address bar also being the search bar tho. Thats nice. Tho again to be fair, I can do that with my IE. I just type one word of a web address (for example, YOUTUBE) and hit enter and it goes to Youtube. If it can't find a site with that name, or i've spealt it wrong, it shows me Google search results for that word... Granted the GC one is a little better in that you can type a sentence into it as you would into the search box.....

I won't be using it as my full time browser - I'll stick with IE7 for that, and I share that duty with Safari aswell which I am using more and more... But I'll keep an eye on what features GC comes up with over the course of it's development.......
