Windows XP Pro 64x

Some readers may know that I've been considering building my next PC. I've decided to go with a 64 bit processor, probably AMD as Intel will be too much money when it (finally) comes out. I've been toying with putting Windows XP Pro 64-bit edition on the PC as my operating system. As this report by Paul Thurrott points out, I may want to hold off on that considering the software and hardware concerns he raises. I'm in no rush.
