I heard that vista 32 bit can only recognize 3 gb, but vista 64 can recognize like a 200 zillion gb. But 64 bit system are a pain to look for new printer driver, incompatability with unsupported printers, scanners, etc.
An interesting article on memory on a 32 bit system can be found here:
http://www.codinghorror.com/blog/archives/000811.html I blame driver compatibility in 64 bit systems on the manufacturer of the device. Most of these people are slowing down the adoption of 64 bit devices because they do not want to keep pace with technology. Just look at how long XP 64 bit has been available, yet many companies still have not made 64 bit drivers.
