I'm no MS fanboi, for sure, but Overzeetop has it right here - the docking station is one of the best features of the Surface Pro line. Combined with the pen which allows a whole new kind of computer interaction, it truly changes the way you work with computers.
Macs are fine computers, but there is no Mac that can even approach the kind of power and utility you can get with the Surface Pro 3 or 4 or Surface Book. The SP4 is more powerful and far more useful than the MacBook Air, and the the SB is likewise superior to the MacBook Pros. I bought an SP3 when it came out, and it absolutely changed the kinds of things I could do (and more importantly, wanted to do) with a computer.
If you haven't tried living with one (especially with docking stations at home and work), then you really just don't get it. There is no laptop I'd trade for. I want all my computers to work this way - the SP4 is as far beyond a regular laptop as the first thin and powerful laptops were beyond clunky old desktops.
Don't underestimate the power of moving the context of all your work to wherever you are, and getting a way better experience when you're docked. It's really amazing. While Win10 still has some pretty ugly seams showing where they lashed the UWP apps onto the desktop OS, it does produce an experience you just can't get anywhere else.
I'm really looking forward to the updates coming in a couple of weeks, which should also enable Ubuntu on Windows for everyone with Developer access enabled, not just those on the Fast Ring of the Preview program.
