I'm sure that you have probably made a decision on a tablet already. But, to answer your question I am successfully running BT5 ARM on my Toshiba Thrive. I gave a brief tutorial in another post in the ARM forum. As long as you have rooted the Thrive, have Better Terminal Emulator, VNC Viewer, and BT5 ARM you will be able to make it work. I have been asked a few times if there was any lag, and I could graciously reply no---what about on your iPad?

If anyone is interested I can include links that I used from rooting to VNCing into the booted ARM, that made it easy for even the basic user to follow.
