I still have my iPod Classic too. The 160 gig model. I use it constantly.
I have the 80 GB one, still has plenty of space on it, LOL! I do have a few movies on it. It’s great when you’re on a long flight.
It's basically acting as a music server for my car. I can stream music but it tends to run up the data usage on my cell phone plan. So having a device dedicated to music storage still comes in handy.
I just hit SHUFFLE on my entire library when I get in car. It's still pulling up songs I haven't heard for years.
I also have a drawer of older iPods that I haven't turned on in ages. I'm sure they would still work though.
