The July issue of Mobile magazine has a list of the Top 100 Forgotten Gadgets.

These are gizmos that either failed to catch on for any combination of several reasons: because they didn't have enough marketing or distribution money behind them, because they got outraced by better solutions - or because they like didn't work.

Here's a summary listing culled from the Top 40 listed Gadgets with functionality (or lack thereof) relevant to what we talk about here. If any evoke special memories, be sure to post a comment:

7- Cobra Dynascan Cordless Phone;

8- Texas Instruments TI-81 Graphing Calculator;

10- Timex Sinclair ZX-81 (a primitive portable computer);

19- palmOne Treo 600 (yea, I was wondering about that one as well, but I guess the 600 made the list because it was soon superseded by the popular 650);

35- HP 200Lx PDA. 1996 vintage, and ugly.

If you're wondering what was #1, I'll only provide limited information. According to Mobile magazine, the cited device was developed in the late 1800s to "treat female hysteria."

Got it, right?
