Hi everyone, I'm going to be making a purchase on one of the new 13" 256GB MBA's when my next pay day hits, and I was wondering which one of the configurable upgades (can't really afford to do both) would give the most noticeable speed difference, and provide the most future proofing. Should I opt for the 2.0 GHZ i7 (up from 1.8 i5 - £120 extra) or the 8GB RAM (up from 4BG - £80 extra)? I work in TV production so out on the road I will often be working on multiple documents, researching using plenty of active tabs in Safari, as well as running iTunes, Twitter, Mail, Skype, Dropbox, Bowtie etc. I will also be needing to do a lot of transferring of footage from CF cards via a card reader to external drives (yay for USB 3!). Outside of work I do a bit of photo editing in Aperture, but noting too professional, just the odd polish and tweak here and there. It would be nice to have that option when I'm mobile, but I can always do it on my iMac if it will be too much heavy lifting for the Air. Any advice appreciated. Thanks!
