connect via copper(cat[56]) no you can't.

Tried with a cingular phone.. yup

I have a slvr.. I can get DUN working, but its only 2G so its painfully slow.. but better than nothing.

As for midi, don't know. However I think you may be looking for just a bit more out of the tablet than is there.

Don't get me wrong.. I love mine, and when I travel, and its not for work, I am not even taking a laptop. This thing will give me all the computer I need on vacation, even ssh back to servers and what not.
