I have an 06' MBP 15 inch. It still works great and everything and I feel its time to upgrade to a newer machine and sell this one before it craps out. I only use the computer for music, internet, microsoft office, and minor photo editing since i just picked up my first nikon DSLR (or whatever its called). Clearly I dont need much power, so i figured it be great to get something light and with all the overwhelming positive reviews I am ALMOST set. but... I will be going from a 15" to a 13" screen. I will lose the backlit keyboard also. So to those who took this similar route, did you miss the downgraded screen real-estate? I hear that MBA are being upgraded soon so I am hoping for that backlit option but ultimately i feel it wont be a true deal breaker for me.
