Last December I made the transition from Mac to PC. It was painful, but I did it. As it turned out it was just to painful and now I am back to Mac.
My new Mac is a Mac Book Pro, Dual 2G with a 7200rpm 100G Hard Drive and 1G RAM. This is one fantastic machine. What is spactacular is that I can dual boot into Windows XP for those times I need to code .NET stuff. This system runs cool and quite and ith the dual core processor and 7200rpm drive it handles .NET, no problem.
The HP Pavilion ZD8000 was my first step away from Mac. Of all the PC’s I evaluated, this was the best. Howeve, having said that I found several annoyances that made me change. This system is heavy 9+ pounds, and runs very noisey (three fans) and hot. Its great if you live in a cold climate because it can also function as a space heater. Here in Arizona it quickly heated my office to uncomfortable temperatures.
I next moved to a Compaq V2000. This is a really nice little system. Runs cool and quite. Its light weight and easy to transport form place to place. However its a little underpowered. Bumping memory to 1.5G helped, but when using the .NET development environment it made you wait while it did stuff. With a dual processor, this would be an excellent system.
