Bluetooth is easy: Samsung P3 or M1. Cowon S9 or J3. None of these have WiFi.
Wifi is limited, and these don't come with bluetooth: Zune HD. Sony X1051/1061.
Apps: The Zune has a few. The Sony has none.
You'll have to move up to an Archos 5 Android Internet Tablet to match the features you want, except that it will be larger than the Touch.
