Looking at picking this tablet up. Just had a few questions. Can you play video from external usb storage (Eg. USB Flash or External HD) just like you would from internal storage? Same thing with music. Also, is there a good streaming app to stream from my media server (Windows 7) to this device? My wife has an iPad and I always use the stream to me app on it, I'd like similar functionality. A500 vs Transformer - Other than the IPS screen any benefit you guys see other than the keyboard? Don't care about the keyboard.
