I've never liked my Macbook Pro for recording. Part of the problem has to do with having used PCs for 50+ years before I got my first Mac. Part of it is that my screen is too small. And it's partly that I've skimped on the software I've used for recording. I've never been happy with the recordings I got on Garageband--not its fault; it was my inability, I'm sure. But often, i've needed software that can do more.
I am partial to the experiences I've had on a PC, but on paper, the Mac is more reliable and in many areas so much better for what I want to record.
So I'm thinking of going with the Mac desktop with a 27 inch retina display and all the power I could ever want. It's expensive, but I don't want to go half-assed with this stuff like I've always done.
And I'm going to find a great DAW. I'm sick of making do with shitty software. I don't mean Garage Band; I do mean at least four other programs I used, can't even remember their names now.
