I agree. I still say the C2D and 320m makes the most sense right now. However, I don't want Apple to add battery performance to the MBA. Batter requires the weight of the 13" MBP. Anyone that wants a 10-hour Mac notebook has to carry around a 1" thick computer with the added 1.5 lb over the MBA. I think a 10-hour battery is ridiculous to begin with, as I would bet the vast majority (95%) use more than half the capacity on rare occasions only.
If one thinks about it, the reason the 13" MBP and MB can have a 10-hour battery is they're thick enough and heavy enough to allow it. I want the MBA to have same performance characteristics as 13" MBP and MB. I don't want Apple to take away performance capabilities to give the MBA a 10-hour battery capability. I don't think most are being realistic here. I would prefer Apple not bog down or thicken the MBA nor remove its capabilities to get a 10-hour battery which is pointless for the vast majority of people anyways.
I will be devastated if we get a 10-hour MBA. I will know that it means we have compromised performance, weight, and thickness to make that MBA happen. That MBA is already available and it's called the 13" MBP. Apple needs to leave it at that and tell its customers the honest truth which is what none of the MBA customers are considering when they expect it.
I want 10 hr battery life in the mba and if it is not offered then I would go 13 MBP. ipad has it and 13 mbp has it the air should also have it. I would not mind a slimed down pro as the new air. take out the optical drive that will save room for a bigger battery.
