I am perfectly happy with my MBA, but I must admit that I like to always have the "latest and greatest". The new MacBooks look great, although I haven't seen one "live" or had the opportunity to get hands on with one yet. If I buy a new MacBook, I give up the form factor, but gain the processor power, features, etc. Also, it will really feel like a new computer because of the different appearance. Since I like the MBA form factor, I was thinking of just upgrading to that. The problem is that it won't even feel like I got a new laptop, because visually it would be identical to the one I have now. In fact, the reduced battery life may not offset the benefit of larger HD and improved graphics. Dying for a new laptop though... what are you other MBA owners thinking?
