I'm no sys admin, but I'd love to have something like this as a true 'Pocket PC'.
I'm not interested in having it act as a phone - I generally find I that if I'm making a call I need to do 'stuff' on the screen that I can't do when I'm holding the thing to my head. Phone and PC as separate items makes more sense (BT headsets suck).
But as a tiny laptop.... now you're talking. FAR easier to carry around than any tablet with keyboard combo, or iMacAir/Netbook - if they stick a 'TouchPoint' (other names are far better known... ) cursor control onboard as well then I think I'd be throwing cash at them now.
