Leo makes some great reasons why not to buy it like how M$ is paying record labels a percentage of sale of the players.
But I don't agree with him on the downsides of the wi-fi though. What players can buy songs over wi-fi or surf the web… ah none. It's kind of cool that you could share songs (pictures, video) with fellow Zuners, the downside is trying to find one :-).
He's right about the DRM being a pain, but that's true of any closed music store system. People have no problem getting nailed to IPod DRM but the reason they are all off on the Zune is that they know their investment in ITunes is useless outside of the IPod. I just hope for all those IPoders ITunes never dies or they are stuck with a capital "I". Another downside to ITunes is for the time being able to buy videos is solely an American pleasure. So bittorent still has a place in my heart.
