Then it's more than I don't really have any use case for it. Either I need to just check something quickly, my emails, something on the web, watch a video, read some text, and then the ipad experience is just fine (though perfectible). Or I need to produce content, write emails, prepare a presentation, write code, work on a spreadsheet. Then anything that doesn't involve a mouse (with its precision) and a keyboard is unpractical (and the surface pro keyboard is pretty bad). Even for taking notes in a meeting, nothing beats the pen and paper, I don't really need any advanced feature (my notes are always at most a reminder of follow ups), and I can't (and shouldn't) focus on the meeting and play with a computer at the same time. But I don't have the feeling I am working in a fundamentally different way than 99% of office workers.
I just don't get what is the use case for a surface pro. Graphic designers possibly, but they usually don't work on a tiny screen, and it's a niche market.
