Stupid. Stupid stupid stupid reasoning.
I’ll do some comparison for you:
Mp3 Player:
A $199 unit will probably get your 64MB of memory, which is less than an hour of CD-quality music (although you can compress the Mp3 to less-than-CD-quality and get a couple hours easy). Additional 64MB cards will cost you more than $100 or so. Also, they require you to go through your computer, DL or burn/encode the music you wish to include. Finally, since you won’t have more than one or two separate memory cards for music, you won’t be able to get new music without going back through your computer and transfer stuff all over again.
Minidisc player:
A $199 player/recorder unit comes with an optical/digital line to connect to portable CD player or home music system and an adapter so’s you can record Mp3’s off your computer. Individual MD’s cost only a few bucks, and each disk carries 76 minutes (or 152 minutes in Mono) of sound at CD-quality (except for Mono), so you can have dozens of hours of music available for the cost of a 16MB (half an hour of sound) Compactflash card. There are moving parts, but the way the MD is set up would require you to hit it with a sledgehammer to get it to skip, so skipping is not a problem.
In short, MD is the better medium… less expensive overall, more versatile, and it gives you more music. Also, the Minidisks themselves look a helluva lot cooler than a Compactflash, Smartmedia, or Memory Stick (they used MDs in The Matrix, you know).
Also, you can probably get just a MD player (no recording option) for about $130, but then you’d have to buy MDs pre-recorded, or have someone else record them for you.
(Yes, I do have a MD player, from Sony… I’ve had it for two years now, and it’s still running on the same rechargeable battery, I’ve never had any problems with it, the control unit is still in prime condition… it’s my baby.)
