What's your most underused peripheral?

[DanFungus]

1 & 2 joystick, gamepad (same level of un-use)
3 & 4 scanner, speakers (I use headphones, so yeah)

DVD, Floppy, Zip and Scanner were all a waste on my system. so $200 wasted dumb.

Best peripherial is my portable 20gb USB2 3 1/2 inch harddrive. If you move files between work and home this is a great solution.

300 baud modem for Atari 130XE
100 Meg zip drive
It's a close call on which one is more useless
