I've had a 40 gig one for a few years and love it. I can't do the gym without it.
At home I have the Apple Airport Express hooked up to my home stereo so that I can steam my iTunes to it.

And the Air Click to control my laptop so that I don't have to walk to my office.

I've tried a few of the FM transmitters for the car but we don't have any free frequencies to use so they all work like crap. On the 16 I'm having the Alpine head unit with the iPod interface installed into my Vette so that I can just plug my iPod into my car stereo and control it from the head unit.
This is what I'm getting pt in my car on the 16. I'm not buying any of this from the internet but I did Google the stuff for reviews and such.
