Unless the manufacturer of your hardware has drivers for Win7, don't bother getting it. If you install Win7 64bit, you'll find a number of companies, such as Canon, Epson, and HP, will not provide 64 bit drivers except for their newest equipment. And if you try to install a 32 bit driver, as I did for my Canon scanner, the install process says it won't install 32 bit drivers and shuts down.
Oh, and don't Microsoft's virtual machine and XP mode either. I tried over the weekend, and the install stall puked on 32 drivers.
