The Surface book and iPad pro are like complete opposites in terms of usage. The Surface book is more of a laptop 80% of the time with clipboard/something-like-a-tablet usage 20% of the time. The iPad pro on the other hand is a tablet 95% of the time and a tablet with keyboard attached 5% of the time. The surface book runs Windows 10 with a discreet processor a la MacBook Pro when in laptop mode while the iPad pro runs ios9. The surface book is a full x86 design which means full desktop apps while the iPad pro is a full ARM design running optimized apps for touch/tablet. Nobody says you can't have both of the products. I like that Microsoft made this new Surface Book and I think it's a great product. I just don't think they will sell that many of them due to price and functionality. The iPad pro on the other hand is basically the same design as the rest of the iPad's which are really familiar but just larger. I think Apple will sell a decent amount of iPad pros but not as many as they may be expecting. While I do like some desktop apps, I just find that a lot of them are timesinks due to their UI/UX design. Tablet style apps designed for the device they are being used on seem to be more workflow friendly which means a faster but possibly slightly sloppier end result. The average consumer doesn't really want to buy either of these products but professionals depending on their needs are more likely to purchase one of these products or even both. I'm more in need of an ultraportable solution that doesn't require boot times, has basic apps that can get the job done and upload via mobile so of course, that's the iPad Pro. If I was looking to run DxO, Photoshop, Lightroom (iOS version is still pretty crappy, why can't Adobe just put in all the functions like other app writers?), and whatever desktop software while in the field, the surface book would have been an easy choice.
