After briefly using one the other day, I really feel like the biggest compromise is the keyboard and let me explain why. Most people who buy a machine like this don't need the fastest machine out there, or many portsbut the primary benefit of buying something like this over an iPad Air 2 is having a built-in keyboard for sitting down to get work done, in addition advanced multitasking and professional apps. Having gone from the old keyboard to the chiclet keyboard back around 2009, that transition was different but not this severe. I'm usually not sensitive to differences in keyboards like some people are, but this keyboard just feels weird. Maybe with a lot of time I could get used to it, but I feel like something like this would be much better matched with an iPad Pro Smart Cover. It would be there if you need it, and provide a faster typing experience than a touch keyboard, but it shouldn't be used full-time on a Mac. Or maybe I'm completely wrong, and this thing is supposed to be used like a tablet that just happens to not have a touch screen that comes in a laptop form factor. I don't know. I really like the idea of it, but it's going to be a few years until it matures. I think what I really need instead is an iPad Pro that has a keyboard Smart Cover and pressure sensitive drawing stylus paired with some more professional apps for photo editing and drawing.
just buy a zagg keyboard case for your ipad, TA-DA you just saved yourself $700.
