Are you only considering the hardware/price, or also the software side?
Which OS’es do you have experience with, and/or preference for?
The previous Mac I used was the first one they made with a colour screen (yes, I’m that old). Then last year I got a Mac laptop and I wanted to love it … but man, that OS is getting in my way something fierce! To such an extent, in fact, that I switched over to my own (arguably inferior) Thinkpad that’s been running Linux since forever.
