i want to buy a Mac. I wrestled with the idea of an iMac vs MBP, it's just that I live in a small apartment and don't have the room to get a desktop setup. Aside from basic computing, spreadsheets etc, my main use would be direct recording guitar, bass etc using my line 6 modeling amp. Couple questions for you guys 1. Is it better to choose the 15" model with the quad core/upgraded ram? Or is the 13" enough? 2. I read about intel's new sky lake 6th gen processors and they aren't in the MBP yet? Is this a bad time to buy right now?
