Microsoft Surface Pro, do you have one? Opinions?
I have an original Surface (first generation), an iPad and a Surface Pro 3 (and a laptop of. purse).
Can the SP3 do what you describe - yes.
I use the SP3 in lieu of my laptop for most trips. The exception is if I am planning to do a lot of work (then I prefer the larger screen, keyboard and wireless mouse) or if I am working with Excel because screen size is then more important to me.
If I am taking the SP3 that is all I take. If I take the laptop then I also take either the Surface or the iPad for movies etc enroute.
