Updated with iPhone friendly video from WMExperts (irony!).
Would you watch un-skippable ads on your mobile device in exchange for free apps and games? That's the question we're pondering in light of Zune HD doing just that. You pay your hundreds of dollars for the device, and Microsoft provides a few extra games/apps, but sometimes an ad will play before the app launches, and you can't skip them. See the video above for an example (apologies to those on the iPhone, we didn't make the video, so have no control over the iPhone-unfriendly format).
