Re: I did like the medical software, but that was about it.
You can't get 10 hours of run time in a sleek format running OSX.
It's a desktop/latop OS, not a tablet OS.
I'm sure Apple is working towards convergence (it's very obvious if you follow the efforts in OS X and iOS on a more detailed level), but we aren't there yet. I don't think Apple wants something half-baked like Windows 8/10.
For creating artwork on iOS you have apps like Procreate, which would be a small fraction of the cost of any of Adobe's OSX offerings (which you have to RENT ffs), BTW. (Who would want to use desktop programs on a tablet anyway? I'm sure some do, but it seems like torture to me.)
