iPod Classic 160GB from 2007. The big, thick one (later 160's were thinner). Played basically every day for eight years, often for hours at a time. I have no complaints. But after choking and stalling more and more frequently over the past few months, it finally locked up for good and won't reboot.
So... the biggest of the new ones (iPod Touch 128) has 75% of the capacity, which may have to be good enough. It has the advantage of being solid state, which I like, and the disadvantage of costing a shitload of cash and including a bunch of stuff I honestly don't care about (camera, apps, Bluetooth (although I might ultimately use that)).
There are also (supposedly) new Classic 160's out there, on Amazon, Ebay, etc. Advantages include price and capacity of course, disadvantages include same hard drive tech and no way to be sure that it's actually new.
Then there's the option of going with a different mp3 player altogether. It doesn't have to be an iPod; iPod was just the biggest, and I have a lot of tunes. I've heard good things about Zune, but that was years ago, filed away in memory for when the iPod finally died. I don't know how they are now.
I'm old school; I have to have my tunes, in some kind of physical medium, to take with me. For practice, for in the car, etc. What are my options?
