Most of my gadgets are built into my computer, but I have a PS2 in good condition and an Xbox I plan to start hacking into soon (maybe get a new "computer" out of it). Ironically the 2 strangest things I have were also the two cheapest I can think of. Cheap doesn't always mean low quality!
#1: Innovage Corded telephone
Price: $12.99 @ Walgreens
Reason: The numbers and math buttons (along with a couple others) on the front panel litterally take NO pressure to activate. You just touch it and it takes the input. Minimal effort, same result. Plus the built in calculator, and funny hold music (it is hilarious, I once left a telemarketer on hold for 15 minutes or so while this annoying jingle played... the hold music will drive anyone insane).
#2: Unknown-brand florescent light
Price: $8.95 @ Lowes
Reason: It is simple, compact, and the part that is really cool is the on/off "switch" is a heat sensing alluminum ball - you just barely touch it and it switches on (or off). It is really bright too, and you can put it almost anywhere.
Couldn't find an image, sorry
Also, I have a Waterpik as well - they do a really great job, as long as you know how to use it (and don't go cranking up the pressure like an idiot
). They really do make a difference, if you can't floss or if you have braces/some other dental adjustment. I have this one:
