I'm thinking about a Zune 2 purchase as well, but not for the audio store (though it will be DRM-free). The Zune 2 has some great video features. There are plans to release TV show subscriptions to sync with a 80GB Zune 2 for watching on-the-go. And why on Earth would you buy a TV show from the iTunes store only to watch it maybe twice?? A subscription model makes so much more sense to me.
Secondly, with Windows Media Center you can record shows for playback. Integration between the new Zune firmware and the WMC will let you download those recorded shows (unpurchased! Just recorded from your DVR!) to a Zune 2 to watch while mobile.
And then there's the other advantages like radio and WiFi syncing. If Apple would step up its video offerings instead of the stupid buying-only model I would get a Touch and be done with it. But since Apple TV, iTunes store and the Touch don't offer the integration that a Windows system will have, I'm going to build a Windows Media Center PC, use that to record shows/have movies ripped and ready to go, and get a Zune 2 to tie it altogether in a mobile platform.
Apple needs to get its Shiite together because its missing a big chunk of the pie when it comes to audio/video consumerism.
[Flip side: no library yet exists for these TV shows for Zune, the battery life on the Zune 2 is less than a Touch, the Touch arguably has a better interface]
