I have been struggling with this because as a designer, it's nice to be able to lay the pro down flat or at a low angle with the kickstand and I would be worried about breaking the hinge on the Surface laptop screen if I tried to really get in and draw with it. However....as much as I love the Pro its "lap-ability" is a little lacking to me. I also do a lot of writing (love the Pro keyboard for what it's worth), but it is really hard to beat the straight up "work on any surface" ability of a true laptop. And call me a fan boy but the design of the Surface Laptop is reallllllly drool worthy to me. My biggest request was a longer battery life than the SP3/4 and they BOTH deliver on that end so either one will make me a happy camper. Now just to decide which one...
