I'm a SansaClip kind of guy living in an iPod Touch world.
It's true. For our anniversary this year my beloved and I eschewed the traditional gifts so she received a countertop ice cream maker (for churning out lo-carb coconut milk ice creams) and I received a SansaClip with a whopping 4 G of memory. I brought it into work and had a fleeting thought to show someone... but then realized that this is a bottom of the run MP3 player. That's all it does. Well, plus FM radio. It plays music and nothing more, and that's all I need it to do. But I work in a tech firm so it's quite common for people to stand in line to get the latest greatest at midnight, fully loaded with all the latest options that will come at no extra charge in six months when the next latest and greatest comes out. "Watch this... I can start my car from three time zones away!"
However I should point out that technologically I have advanced to the point where I no longer use my Sony Walkman. Or rather my Panasonic Cassette-2-Go player.
