So, my main computer is the 15'' rMPB (June 2012 model, with the 2.6GHz i7), and it suits me really well. I've recently started doing a lot more high-intensity writing, though, and I'm looking at getting a more portable second machine so I can continue to work away from the desk without lugging the MBP around. I'd previously looked at the retina iPad due to its portability and my eyes being used to retina screens now... but I've been kind of wary of how useful it would be without an iOS version of Scrivener to work with. With the release of the new MBA with its improved battery life, though, I'm now leaning instead towards the base 11'' Air. At the moment, I'm looking to be upgrading the RAM to 8GB but keeping the base 1.3GHz i5 processor. Given that I'd be using this as a secondary machine predominantly for writing purposes, and bearing in mind I'd get an academic discount on macs but not on iPads, does this decision make sense, or would it be overkill? Would I miss the retina screen? And if it is the right call to go for the Air, am I right in assuming that the RAM upgrade is worth it but the processor is not?
