As title said: I have a really beefy 2 years 17" Windows 7. It's my primary system. I've been looking at MBP 15" or 17" for a while and I decided to go with MBA after many positive review. I have got my MBA 13" Ultimate for little over two week now. Within that time, I have been using MBA pretty much for everything. Is MBA really a secondary system? I have been asking myself this question lately. Since I got MBA, I turned on my primary system once!!! that was just so my wife can see that I am still using it and needing it. But, really... that's all I did, turned it on and walked away. Is this phenomenon because of MBA is a new toy? is this a short term thing? or am I really happy/satisfied with MBA and no longer need my primary??? Do you MBA owner feel this way?
