Hi All, I'm not surprised I'm yet to see any comparisons on this given it's very specific, but I need to make a buying decision on the MBA or rMBP. However, and I suppose/hope many are in similar scenarios, if we remove portability and screen from the equation, which is the better machine? Which machine will perform better driving an external monitor (as primary and only screen). Here are some more considerations - I use the laptop for personal and work and I work from home 80-90% of the time, and travel the other 10-20%. This means 2 things. (1) I intend to have the laptop plugged into an external display and have the laptop closed when I'm working at my desk, so retina display is redundant (2) Portability (size differences) is redundant given travel is relatively light (however needs to be portable for travel, hence a laptop as opposed to a desktop). - I mainly do 3-4 things on the laptop (1) Work (email, lotus notes, word process, excel, powerpoint) (2) large mp photo work in lightroom, light video editing in iMovie (3) Personal email, social network, browse etc on Chrome (4) Listen music, youtube etc - I would be speccing out (BTO) either machine, so interested in either the (a) 2.2ghz i7 w/ 8gb RAM MBA or (b) 3.1ghz i7 w/ 8/16gb RAM rMBP - I currently own a mid 2011 MBA with 1.8ghz i7 w/ 4gb RAM (the poorest performing MBA that came out ha) So that's my question. There's lots of reviews that heavily take into consideration both portability and screen, but given they are redundant in my scenario, I'd be interested to hear any real world experience or opinions on this. In your response, it would be super appreciated if you could rationalise why one is better than the other, whether conceptually or in technical terms. Thanks so much all.
