How do you listen to music while out?

I kinda want to update the way I listen to music. I use a 2007 iPod Nano, 8gb, and it's served so well, outliving an iPod Touch easily, but I don't like having all my stuff on 1 device for some reason, plus I love the tactile feedback you get from an Apple clickwheel.
How outdated am I?

Why don't you like having your stuff on one device?

Battery, lag, having to exit apps to change music etc, plus if I don't wanna take my phone somewhere (I left it in the hotel room most of the time I was away the last few days) I can still have music.

I used to use a latest gen iPod nano which was a pleasure to use. But then iTunes stopped recognising it and I lost it. Tempted to buy another one, actually.
