the fan is quiet, and it hasnt felt hot.. I haven't played with it TOO much so I'm not really a good judge to say yet 🙂 as for wi-fi, it works better than my black macbook.. but my old one has been slow today anyway for some reason. I would guess the speed is about the same.
I wish I just put down 1300 to get rid of that 🙂 unfortunately I got the high model so with the student discount and tax it STILL came to 1564 or something. I'm actually on my way back to the apple store right now to exchange it because when I opened the box, it had another layer of tape that was already cut open. I thought it was weird, then when I started inspecting the aluminum there were weird chips in a few spots. It started to bug me because I feel like it was opened when it got there and something chipped it, so they agreed to exchange it without the stock fee. Hopefully by tomorrow I can let you all know how the fan/heat is.. but I'm sure most of you will be getting yours in the mail by then!
