Oh, I know what you're talking about now. That has nothing to do with the OS or the hardware. It's the coding that HTC has done. The reason it appears "smoother" on WinMo for you is just like you said, you think the Sense on Android is abrupt. But that's just how it was made. Personally, I like the abrupt, quick animations better because I feel like I'm waiting for WinMo to catch up when they are slowly smoothed. The Android Sense seems faster to me because of the abrupt nature.
