I am looking to buy a MBA rev. A with 80GB HDD then I want to upgrade this with SSD to speed up the machine. I don't care about GB's as long as I have 16GB ish. any aftermarket SSD that is compatitible with MBA rev A? I heard Great things about Runcore. But Any other options? thx in advance PS: Would this work? http://www.memoryexpress.com/Products/PID-MX27150(ME).aspx PS2 Would it be a good idea to buy one now? or just buy REV.3 refurb? No probs watching Youtue HD??
