I am looking to buy a new power book. I am going to use the airport extreme card a lot and was wondering since the case is aluminum if I would be able to get a good signal compared to a dell laptop. How good REALLY is the wifi signal you have experienced on the new power books? Also, I am looking for a program that could mount a CD image to the HD. I want to play my games such as Halo and UT2004 without putting the CD in. Does anyone know of a good free program that does that. Thanks so much for all the comments! It is much appreciated.
