Mr Fretwell got my old dell laptop and I replaced it with a Macbook pro. Hours of battery and never gets hot even on the power supply and running graphics for hours. the whole chassis is aluminum. Fabulous design and runs Windows better than most PC based computers once you get past the Apple specific drivers for their hardware. I have met a couple of guys that bought macbooks and pretty much did a minimum mac install and dedicated most resourses to windows. One fellow said his MB pro with a 2.0(?)mhz dual core is faster than his toshiba with a faster processor and more memory Ie 2gb on the macbook and 4 on the toshiba.
I don't really notice the speed since I still have internet traffic to contend with but I am impressed with the macbook pro.
