That's an easy one if you don't care about VGA then just go with the X30H.
The only thing you'll lose is a little x50 styling and a CF slot. But you'll gain built in wifi :) plus my x30 hasn't given me 1/10 of the head aches the x50v has.
I don't think any of the MS software has voice direction. There are only a couple of companies that have voice direction. If you want voice direction then I would go with the Dell package I think mine was about $180 and then the BT dock was $85.
Btw there are a few links around here that will save you some dough
