Oh, yeah that brings back memories. I personally had several Aiwas. My first one was a birthday present from my parents. I was one of very few privileged kinds in my school to have one.
It lasted pretty long (can't remember how long) and was still working long after I upgraded. Back then, new models didn't come to market so quickly, it is was possible the highest-end model would keep their top spot for at least 12 months, but my original aiwa kept working even after someone stole my newer player.
Traveling with it was a hassle when I stop to think about it now, but I guess back then, it just meant that I either stuffed more things into my backpack, or really planned what I wanted to listen to.
As many of you have mentioned, the best feature was being able to record on it. Making mix tapes, my own audio logs and even recording a Michael Jackson concert when he was in town. Yep, it was a very useful device out of the box, to me anyway.
Eventually, I graduated to MiniDisc, but I nearly went DCC (anybody remember DCC from Phlips?) CD's were playback-only, and back then CD recorders were horrendously expensive, and I guess I was really into mixing my own music then, so portable CD players never really did it for me. I used the 3-disc changer on my home hi-fi, made a playlist timed exactly right, and recorded via the optical-out to my MiniDisc recorder.
Of course, now I own several iPods and an iPhone, and am waiting for the 3G S to be available in Singapore where I live.
As far as I know, recording capability is a feature missing in many mp3 devices, ipods included, and only recently implemented in iPhone 3.0. Not that I really need it right now, but it was a feature that was almost standard throughout at the end of the portable cassette player's life. Just add mic.
Aah... the memories...
As a sign of the times, and as examples of companies tried to resist the tide of change, Sony is now in trouble, and where's Aiwa now?
