I have an iPod. But if you don't like them or want a change, get the Zune, I would recommend it. Zunes are awesome music players and you will be happy with it. But let me just tell you a few pros and con, just in case.
Zune:
The good: The Microsoft Zune has very good playback performance of audio, video, and photos; intuitive and colorful interface; good FM radio with RDS; works well with Zune Marketplace software; integrated wireless allows sharing of songs (limited) and photos; many accessories available at launch.
The bad: The Microsoft Zune is not backward compatible with WMA-DRM9; weak native video support (cannot play protected content) and no video offerings from Zune Marketplace; cannot be used as a hard drive (and no UMS support); proprietary USB; cannot use Wi-Fi to sync, stream, or purchase content; minimal bundled accessories; no podcast directory; maximum capacity is 30GB.
The bottom line: The Microsoft Zune with its intuitive interface and solid playback performance will please most users. But lukewarm format support and the cool but limited Wi-Fi capability will have advanced users seeking more. The Zune is a very good start, though.
