Well, I'm getting impressions of 2.2 from two ROMs I've been working with, both of which I've seen many here post about: KaosFroyo and Cyanogen. First I'll tell you what I did with them, then I'll state my impressions of 2.2 on my Eris. - overclocked to 710/710 with sleep profile at 245/245 - ADW launcher remained - via Root Explorer, pared it way down of apps, leaving only the "safe" ones and the few I habitually use: Root Explorer, Weather Bug Elite, Transparent Clock, Retro Clock/Date, SetCPU, Meteor (paid) and Launcher Pro (which I did not use with either 2.2 ROMs but downloaded it anyway as I had donated) Honestly, 2.2 seems draggy compared to those same tweaks and apps on 2.1 (xtrROM 3.03). It is fast after tweaking the CPU, but it seems to lack the snap and smoothness of 2.1. I am nearly certain that has something to do with the compatibility of the kernel and other deep aspects of Froyo with the Eris graphics and CPU dynamics, overclocked or not. It is always quite the eye opener going back to xtr after using Kaos for a while; the longer I use 2.2, the more dramatic the difference seems after restoring and firing up xtrROM 3.03.
