At work, in hotel rooms while I'm on hte go, in business centers when I'm waiting for customers, etc. With the restraint of traveling on a plane, I seldom check a bag, my laptop case fits in my lap and my suitcase fits in an overhead compartment. Lugging an extra laptop and it's weight, and it's power supply, isn't something I want to do. Most of hte time I go with my surface alone because it can do everything I need on the road. The surface pro, being a comparable size, would be just as good.

Also it'd be killer if someone made an ultra portable rf controller with dual analogs, that say folds up. Maybe I'll canibalize one of my wired controllers and see if I can make osmething.
