I'm enjoying this browser so far! It's very slick and loads websites and media up pretty quickly, faster than firefox and safari.
I like its capabilities for something in beta, the tabbed browsing, searching through the address bar, and incognito mode, which is exactly the same as safari private browsing (or pr0n mode).
I'm using this on an EEE machine, and have definitely noticed how efficiently it manages its processes, especially if you create your webites in 'app mode'.
The only thing I find thats poor right now is the flash/plugin support, which isn't integrate so well at the moment. It slows down and in some cases comes close to crashing/freezing trying to run youtube video's and do another action at the same time, also noticed flash web games are slow and stuttery compared to IE, firefox or safari
Aside from this, its lovely. Will definitely be keeping a close eye on this. I have high hopes seeing as it already shares some of the same open source code as both Firefox and Safari, and will remain open source
