WM 6.5 is surprisingly very stable but very less apps, also the main problem is WM6.5 docent support Flash 10, but Android supports Flash 10.1 and there is a web browser called Dolphin HD, if u want to watch any video, that browser has inbuilt video player, so its like PC, what i did was i updated the ROM and installed Android that comes for the EVO 4G, then installed an app call "Network" it allow me to run 3G/H as well, net speed is also very good, Airtel gives 1.2MB when i test with the speed test. BTW try Android, u can install it to the Memory card so anytime u can get rid of it, just give it a try and see, you will love it
