Okay, I'm new here. Just got the Air today. 13" 128gb, 4gb RAM. Trying Mac on my wife's insistence. Both of us are long time Windows users, and she said that we HAVE to see what Mac is all about. So, today my Air hangs at least 5 times. I find unresponsive programs etc which I thought was non existent in Macs? Mostly the problem is with iTunes. When I try to add a folder which is on a network drive, it just hangs after about 5 minutes. Another issue is the heat. It is almost unbearable to use it on my lap. Right now CPU is at 80C and enclosure base is at 35C, probably because iTunes is running again. But even with just surfing, the monitor shows base temp at 32, but it is really uncomfortable on the lap. Fan is at 6500 rpm. I so much want to love Mac, and I do love what I have seen till now, like expose etc but these issues are unacceptable? Am I doing something wrong? I have 10.7.2 and have the latest iTunes too. EDIT: Hopefully all problems have been resolved. Crossing my fingers here.
