I've been reading the Air section of the forum for months now, planning my next purchase. At the moment, I have a mid 2009 MBP Core 2 Duo 2.26, which I have bumped up to 8GB. Its running fine if a little slow compared to my 2012 i5/16GB Mac Mini! Am going to replace the battery and pass it on to my nephew as it should see him through the next couple of years at school as a workhorse. However, I cannot decide on my MBA spec. I'm getting an 11" for portability, as I commute to work and use my MBP when travelling to conferences etc. I'm not video editing or pic editing, as I have the Mini with Aperture on it connected to a 24" ACD. So, my options are: Base Air 4/64 - nice and cheap, but I'm back to the age old question - do I need 8GB? The storage is fine, my iTunes library is <10GB. Most stuff is on the Mac Mini. Air 8/64 - is 8GB needed for 10.8? It definitely is on my current machine, but can any 2012 Air users help? Air 8/128 - would be a luxury but I don't really need the extra storage. Main usage: Safari with multiple tabs on the go, much Evernote, Dropbox, MS Office work (esp. spreadsheets), Keynote, streaming Spotify. If Haswell (whenever it comes) brings a big boost in battery life, then I'd be very tempted to upgrade. Hence this machine might only be for 18 months, should I just stick with the Base Air 4/64?
