Yes, they are comparable, if you are going to compare say, a Pinto and a Ferrari.
There is a reason that Zunes have no market share...
I personal am not a big fan of iPods because of the propitiatory nature of them, and how you MUST use iTunes to load anything on them, and you can't really get music off, or share it.
The only mp3 player I have is a SanDisc Sansa, a 1 and 2 GB model, that you can drag and drop mp3s on like a thumb drive. It is nice.
