I told myself I would replace my 2012 MBP if I was lucky enough to get a new administrative position at work, and it was announced yesterday that I got it. Now I'm having a difficult time deciding between the MBP retina 13, the MBA 11, and the rMB. Each has upsides and downsides, so let me tell you what I'll be using it for. 1. Help me take notes at various meetings. 2. Hook into the projector to run my slide shows (I do like to be able to see my lecture notes on screen as I go). 3. Some word processing/powerpoint/excel usage, although the bulk of that will likely be done on my full size work desktop. 4. Watching videos while on trips or back at home before bed (I know they say it stimulates you, but honestly helps me fall asleep..) 5. Any other general work usage that I've not thought of that you guys/gals can identify The downsides as I see them for my application rMB - one port, will need to buy 2 adapters to hook up to the projector (prefer to have power attached for long lectures). Fanless design also scares me as an occasional log in to warcraft for dailies while on trips would be nice. MBA11 - the screen, small hard drive unless I pay the premium for bigger retina MBP - lacks the portability of the previous machines and price.
