Early Adopters Who Got Screwed: [View All]

What new technology did you become invested in (financially or emotionally) that you truly believed in that entirely flopped or is no longer even remembered.

For me there were two:

The Apple Newton.

MiniDisc

(I was absolutely positive that these two gadgets would catch on. I particularly blew a wad on MiniDisc. But I have an unopened Newton that for all I know maybe worth some money--or more likely, worth nothing!)

Under the "It Remains to be Seen" category are these two:

Portable XM radio
Portable Sirius radio

On Edit:

My father believed that Beta Max would overcome VHS.

And his entertainment analyst was hot on Laserdisc.

Another one I blew it on (although I was a teenager at the time) was the KeyPro portable computer. My father urged me to get a Microsoft computer rather than either a Keypro or a MacCintosh. Turns out he was right about the KeyPro.
