My iPod Classic. Its a beauty and holds all of my music.
This. Bought it in 2007 and it's still working well today. So much space, so much beautiful music and a few movies/TV shows. Also have used it as a USB drive in a pinch.
It's also holding up better than my Late 2006 MacBook, which has had two swollen batteries (one replaced under warranty - one sitting on my floor, so I am only connected via MagSafe) and often stutters/lags with multiple tabs open and handling videos. Only in OS X though. My MacBook runs better in WinXP via Bootcamp... sigh.
I've 'been in the market' for a new computer for some time, but I keep finding an excuse to hold off (wait for specials, wait for Haswell, wait for Haswell specials, next - wait for Broadwell?).
