I installed XP about a week ago... it is different to look at from 98 isn't it? I am still getting accustomed to the new look of Windows Explorer, but it is neat that XP finds new hardware automatically as soon as you plug it in, no reboot is necessary.
I plugged in my Christmas digital camera, and it instantly recognized the new camera and opened a utility for viewing and saving the pictures. Pretty durned cool.
Yeah, everythink I've plugged in was like it was manufactured for this computer and this OS. seamless.
