Last I checked, most first revision products have a few issues. Hence, there are three iterations of the EVO out in the wild. I have a rev.3 and guess what, it doesn't have glass separating issues, light leakage or a floppy battery door.
Iphones when first released were plagued with problems too. So, ranting aside, this kind of expected for a product that is less than half a month old. Also, Android isn't near as old as the Iphone OS. Simple as that. There is catching up to be done and if Google would unify the OS across all platforms and remove all the carrier bloatware, Android owners in general might have a better user experience.
Coming from the WinMo 6.1 and 6.5, Android is worlds better.
