I had asked in another question in this forum if i could upgrade my processor but got the answer that its soldered down. I think it would really be a selling point that yes you can upgrade a processor if you want to, I do it on my Windows machines all the time and you can really get some substantial upgraded power. Like in my instance, going from a Core 2 Duo at 1.4ghz to a Core 2 Quad at 2.6ghz, but oh well...my Air flies for the specs it has, the SSD really helps out a lot. Just throwing out an idea, any thoughts??
