Just reading a review of the 11" MacBook Air and noticed an interesting point on why they are likely using the Core 2 Duo while other 11" notebooks are using the new CULV chips (i5 and i7). I know I have been wondering why the Core 2 Duo is still stuck in there, others were expecting the Core i5 or i7. Hopefully this puts any queries to rest. The review mentions that it's so they can use the Nvidia integrated graphics - there must be some sort of restriction/problem why the i5 and i7 all seem to be using Intel GMA video? Sure enough, I looked up the Acer Aspire 1830T-3721 and it uses Intel GMA HD. (Also note that although it's an i5 it is only running at 1.2GHz.) Thank goodness Apple stuck with Nvidia. From what I had read of others experiences and from my own the original MBA with Intel GMA was really a let down & the MBA got so much better when newer models got Nvidia graphics. Maybe this info helps others who are wary of the 1.4GHz Core 2 Duo that is used. It did for me - I'm sold.
