I have a MacBook Pro 2010 i7... I love it but I ABSOLUTELY love the new Air, it's so thin and sleek... I can't forget about it lol. So, I was wondering, if you recommend me changing from Pro to Air? I heard it's fast but is it capable what MacBook Pro is capable of? Will MBP be as fast as Air if I upgrade my HDD to SDD? And can you upgrade the memory RAM and space in the Air without Apple's overcharging, kinda like Crucial or something?
