Think about USB port to connect your keyboard and your sound module.

Yes I am pretty sure the iPad 2 will have NO USB port, even a mini one.
I use the camera connect kit and an Edirol UM1sx on my iPad. I also have the option of using the Line 6 Midi Mobiliser.
But the W7 tablets being released this year look interesting, although battery life is still only half of the iPad...Until they can get that sorted I think they will stay well behind iPad
