Donny, as you ALREADY know
, I really LOVE my 4G 40GB 'click wheel' iPod ! I've tried the other brands mentioned, and I feel 'no other' MP3 player out there offers the SPEED & EASE of pulling up any song(s) the way the Apple copyrighted 'click wheel' feature can. The click wheel feature allows you to operate the iPod with ONE hand alone. I hold it in my left hand, and place my left thumb on the wheel. I need only to spin my thumb around the wheel to search thru the song database. The faster I spin my thumb around the wheel, the faster it goes thru the database. VERY COOL !
Then use the same thumb to press (click) the wheel to load/play the song. How easy can you get.
Apple's unique design is the clear winner here. imho.
Donny, I remember your concern about having to call up any song (in a HUGE database) in under 2-3 seconds. That's not possible with ANY MP3 player, or even on your PSR3000. The smaller the size of the database, the quicker it will be to locate. I can locate ANY (at random) song in my 5000 song database usually in UNDER 10 seconds. If I want to ensure finding it within 2-3 seconds, I would just create a PLAYLIST.
I use my iPod mostly to provide background music during breaks. I'm able to create 'on the fly' playlists from my over 5,000 song database, which enables me commercial versions of the songs I perform on that particular show, or more preferably, 'other' songs recorded by the same artist I might be showcasing that evening.
Though I don't do this myself, you can even create MP3 setlists to perform karaoke style with. I've seen a number of solo guitarists in my area that strap an iPod to their belt, and perform with their Guitar & small amp to backup music supplied by the iPod.
