Hello everyone, I'm in the process of buying my first mac and I'm thinking it will be a MacBook Air. I have not settled on which one to get (11" or 13") but I'm leaning towards the 13" one. I'm planing on hooking it up to my TV via minidisplay -> HDMI and i was wondering will it play 1080p high bit rate videos smoothly, and secondly, would you say its worth getting an i7 upgrade for this purpose? I asked in the apple store and they didn't recommend me buying and Air for this purpose but while researching it on the net it seems like the Air can play 1080p smoothly so I'm confused. They also said i will not be able to return an opened package so i cant buy it and try it out so i would like to hear from some one who has one. Thanks in advance!
