fyi - there IS a second USB on the Surface Pro - it's located on the transformer brick, and easy to miss. No use in the field, but useful at home or location with power, should you need to attach a backup drive or whatever. (plus there are always USB hubs!)
Not yet. And... you have already bought yours?!I like the idea of the SP3 being introduced simply because that mean (I hope) the cost of the SP2 will be lowered.
