HELP!! Decision making after this Surface event

Ok so i have a decision on my hands.

Im really interested in the Surface Pro 2, it seems awesome and finally in more or less the right form factor and functionality to take the leap.

I currently have an order with HP for a new $1000 laptop, and i also have a nexus 10.

Im deciding whether or not to cancel this laptop order, and use my warranty for my nexus 10 which would give me back $500.

Id have $1500 to spend on the Surface Pro 2.

Im just stuck on whether or not itd be worth giving up a full laptop and a tablet. For The surface pro 2 which is basically both in one.

P.S. Id also probably get the dock and leave it at my desk.
