Just curious...why the hurry for ICS? What would it realistically offer beyond the ability to run Chrome (whose feature set is already nearly entirely included in the stock browser)?
I know a lot of people seem to be expecting some sort of outrageous performance increase, but having seen the Gingerbread-to-ICS transition on the Nook Color, I have personally seen no evidence to suggest that ICS will be materially faster than Honeycomb (with the possible exception of slightly less lag in the stock launcher).
Has anyone had a different experience? We can't really compare against the S2 because it never ran HC.
Upgrading from GB to ICS on my S2 made the android experience much better. On GB, touchwiz kept crashing at times and it was annoying and while overall once on 2.3.5 it was more or less stable. But after a slight hiccup with the upgrade (battery drain, some touchwiz crashing), I reset the entire device and from then on ICS has been running quite nicely. The browser is faster, touchwiz is faster and battery life is a lot better than before.
videos of the 7.7 on HC suggest a slightly sluggish UI and sometimes the browser is sluggish according to some sites. I've used a 10.1 and a sony tablet s, and the sony's UI is much smoother.
In videos of the new galaxy tab 2 (both 7 and 10.1) running ICS, things seem a lot smoother, especially the UI. I am hoping that the ICS upgrade on the 7.7 will make it smoother with no jerkiness.
