Thinking about all the gadgets I've owned over the years and the ones I really liked (easy to remember) and the ones I didn' t like (those are much harder to remember).

Quickly coming to mind was the Compaq Contura Aero, a snappy subnotebook that had its trackball at the right edge of the wrist rest -- great for righties, but must have been impossible for lefties!

This was a great notebook for word processing and commuting -- which when I had it was exactly what I used it for -- made my train rides super productive!  I had both the mono and color versions of this thing, but actually liked the mono better.

Check out these representative stats (on the super high-end model):
Intel 486SX, 33 MHz. 12 MB RAM (4 MB on the motherboard plus 8 MB module in expansion slot).Up to 500 MB hard drive. Screen: Color, 640 by 480 pixels. AC adapter. External floppy drive.
