Here are a few of the posts
The SFI from 5.0 was not used so there will not be tabbed browsing or key ghosting.
It will be faster, theme friendly, better memory and battery life, faster broswer, zero lag when typing just to name a few. I have been running it for several days now and it is steady as a rock.
I have been running BBC's V8 (his latest hybrid) and all I can say is wow. If have pretty much punished this hybrid as best I know how and it keeps on ticking. Every app works, excellent battery and memory. Zero typing lag and I mean zero. Browser is fantastic. If you liked 7.1.4 this is a major step up IMO
