Because Windows Me was released to manufacturing months ago, I've had plenty of time to play with it. I've also talked to a large number of experienced Windows users about their upgrade experiences. For new hardware, this is absolutely the way to go. You can be certain that all hardware drivers are the right ones, and you won't have to worry about incompatibilities with older software. Don't upgrade unless you have the right hardware.
Memory is the most crucial ingredient to a successful upgrade.
If your PC is more than two years old, forget about Windows Me. Surprisingly, name-brand computers may have more problems. However, many of those PCs include custom hardware drivers and bundled utilities that were designed to work with a specific Windows version. If you have a name-brand PC, check with the system manufacturer for any upgrade instructions before attempting to set up Windows Me. System utilities can cause more trouble than they're worth.
