November is soon round the corner and my buyer for my 2011 Pro is finally coming good with the money so I am going to buy an Air. I have a student friend who is getting me the basic student discount so the prices are a bit different to what I have seen online, however, I really wanted 256GB but the price difference is insane. I'm going for the 8GB ram upgrade, but not going to bother upgrading the CPU (I have an i7 in my MBP and I bet I haven't even used it at 50% capacity). So the base model with the RAM upgrade is £1079, but the 'ultimate' with 8GB upgrade is £1329, £260 more... So to my question, how do you manage your data on 128GB, and also, what is the installed actual available memory? I used to DJ and produce music but the passion is burning out so I will cut some of the fat when I migrate, but I play a few games (Diablo 3, Minecraft, CS:GO etc) so I need some file space for those and others. And what other post purchase upgrades are available third party? Apple in store prices are outrageous so that's probably out of the question. Is 128 just 'too little' for practical use?
