Unfortunately the first generation of the Surface Book has been plagued with bugs. I avoided it assuming it would need a generation (or two) to get things right. But look where Microsoft took the Surface Pro in two generations. Surface Book is going to be amazing in a year or two. Heck, it might be there now, I hear a lot of the bugs have been fixed...but imo, it's not worth it right now. I say this as a very loyal Surface line customer.
