Looking for some thoughts from users of Rev a or Rev B MBA owners on whether these will run SL OS well. I have a 2.4 Unibody MBP and the 23" ACD set-up at home but was considering the MBA for traveling. Am thinking of seeing how SL performs on MBA when release before making a decision, any advice? They have just released all 4 versions of the MBA on the refurbish section on the Hong Kong web site. The rev A 1.6 is by far the most affordable.
