Please elaborate more how video game consoles are considered an I/O device. They are considered computers because they run on a prcoessor and have a internal HDD.

Keyboards
I'm still clinging onto my Microsoft Natural Keyboard Pro, though it's getting a bit old. It took a little while to get used to the curved shape and split keys, but I love it now. The one thing I hate is that the 6 key is on the left side of the split?! What was Microsoft thinking? Have they never taken a touch-typing course?

It's hard finding a keyboard with just the layout I like. I recently found a Belkin model, which I use at work, which is just right. It has the ergonomic shape, the split keys (6 on the right side), the oversize backspace key, and the L-shaped return key that I like. It looks like this:

Unfortunately, it is PS/2 only. They make a USB version, but it doesn't have the same layout. I feel like the PS/2 port (and mouse port) may go the way of the parallel port, the serial port, and the dodo bird, so I'm hesitant to buy a non-USB keyboard. I know some of the new Dell computers at work no longer have PS/2 keyboard or mouse ports.

Mice
Mice have come a long way. Remember the old ones that had the rubber ball and the mechanical sensors? They would always pick up dust and dirt and hair. Even with regular cleaning, the performance was inconsistent and tended to go down with time.
I was SO happy the first time I ever tried an optical mouse. It glided so smoothly, and the cursor moved with almost perfect resonsiveness.
Although I'm happy with my Logitech MX500 optical mouse, now I'm craving a laser mouse. The laser is apparently able to track better on a wide variety of surfaces compared with a typical LED. There is a technical paper on the differences between these technologies here:
www.logitech.com/lang/pdf/laser_techbrief-04.pdf
My choice would be a Logitech G5. You can find this online for about $46. The G5 supports 2000 dpi resolution, 500 USB reports/second, and has a processing engine capable of handling 6.4 megapixels per second. This might be more processing power than my first computer had. :)
