Kaspar,
Up until recently, the iPod nano only had two watch faces (analog - black or white), which sort of limited its appeal as a watch. And, yes, you have to push the button to wake it up from sleep mode to see the watch face.
Last month, Apple released a software update giving it 16 new watch faces for a total of 18. Some of 'em are pretty neat. The nano-watch is starting to look a lot more appealing:

My personal favorites:
1) There's a simulated Nixie clock! It's almost worth getting just for that!
2) Kermit - gotta love the frog.
-abe.
p.s. There's also finally a decent metal bracelet for the nano instead of just the usual ugly rubber or silicone monstrosities:
