Since the 2.2 upgrade, we were blessed with the lag time to display the home screen icons, as well as populate the app drawer. Its very frustrating. I have read many people trying different things to correct it. None of which have a lasting effect.
I think I may be on to something though. Most of us probably hit the home screen to get out of an app. I have started to use the back arrow button to get all-the-way out of an app. It looks like a decent work around. My home screen lag seems to still lag a bit but only when I pull it out of the desktop doc.
If this does help others, then it looks like the application stack is the issue. I have no other thoughts then that.
