I know I had a CD with drivers for my Logitech G15 keyboard. When the old bedroom machine broke down and I replaced it with the cheap tri-core, I just attached the keyboard without installing the drivers. It worked as a keyboard right out of the box, and the keys glow in the dark as they should. I was just glad to have the machine up and running, so I could live with not having my 56 programmable keys on the side or the multimedia keys on the top or the extra information in the LCD display. But as the weeks went by, I started to miss the luxury, and so I began looking for the CD. I found the original floppies for DR-DOS 5 and some TrueType fonts for Windows 3.11, and many more such things. But not the keyboard drivers. Eventually I gave up and downloaded the newest drivers directly from Logitech instead. It took me a couple minutes, but it would have taken less if I had remembered to look for 64-bits drivers in the first place and not erroneously gotten 32-bits the first time.
One day perhaps the computer will keep track of such things itself, and all we need to do is plug stuff in and it works. But will that be before or after people stop typing and start talking to their computer instead?
