T said back in November 2011 that the S 2 Skyrocket would get ICS in 2012.  But when.

Fragmentation is a huge problem for Android.  I switched from iPhone for the bigger form factor becuse the iPhone screen is just too small to see the web on.  But if Apple came out with a 4.3" or bigger iPhone screen I'd be back in a heartbeat.

Android is worse than windows on pc's.  That market was always fragmented but you could always upgrade a recently purchased machine by buying a new version of windows and loading it yourself because the underlying x86 architecture was the same.  But with every ARM chip maker having differences in how they implement ARM there is no hope for anything like sanity in the Android space.
