hello all !!! one question for the specs of MBA. i'm not a heavy user, i just use excel, word, web-browsing, email and itunes. and usually i have all the afirementiones applications running at the same time. the 1.8ghz and the 2MB ram, are they enough for me ? and something else, there is a growing rumour that the USB 3.0 would be around soon enough. what the implication would be for the hardware with usb 2.0 ports ? best regards to all !!!
