Was thinking of getting a new mp3 player, but changed my mind, 'cos all the new ones seem to use a dumb-arse built in Lithim ion battery - so 40% loss of batt life after a year of use, no way to carry spare AAA batteries with you (or buy one if all else fails), and the thing will basically become useless when the rechargable dies entirely, as it will inevitably do. A hundred quid for something that is basically intended to be thrown away, no thanks.
I like my sony 1G model with 50 hours life on an AAA -despite the utterly crap software Sony makes you use, with their tiresome paranoia about copyright when I'm only ripping my own cds (why don't all those companies with their crappy copy protection systems accept that horse has long since bolted and all they are doing is pissing off legitimate consumers??). But Sony seem to have shifted to this crap LiIon batt concept, and the cheapo players that do use normal batts have shite 12 hour batt life.
But someone must be buying the ones with the stupid built-in batts. Curse you for rewarding bad design!
