I saw a post online earlier about technology that was available when I was younger, and it got me thinking about the technology that was thought of as the 'best' at the time, only to disappear off into the ether months later.
For me, it was definitely this - the Somy MZ-R909 Minidisc player:

I remember buying one of these back in the day, from O'Connors of Galway when it was still on Shop St. If I remember correctly, I think I paid £220 for it at the time - not a small sum of money. At the time all of my money was going towards getting me through college, but for some reason I had extra money at the time, and after a LOT of thought, decided to splurge on myself. It was going to solve all of my portable music problems - I'd be able to run and cycle while listening to music, no skipping, even had a nice remote with display that I could control the player with while leaving it in my pocket!
I spent hours copying CD's to minidisc, playing the whole CD with the MD player on record, then going through it afterwards and adding the track breaks. OR creating compilation minidiscs by meticulously recording one mp3 at a time from my computer.
No more than six months later, portable mp3 players hit the marketplace for the first time, and my minidisc player was obsolete... I think it sits in my desk drawer to this day. I often wonder what kids would think of it if given one today.
Anybody else have tech from the past sitting in a drawer or a box somewhere that was the best of the best for a sort time??
