Just came across this at Amazon, and I'm really close to placing an order since iPod's rarely go on sale it seems. I've been having a tough time deciding between the Touch and the Zune HD, but apps, games, and a better web browser would make it so that I don't have to carry around my big ass laptop, so I think I'm really close to buying it. Then again, a sports talk radio station I listen to throughout the day has an HD signal, so the Zune HD is exactly what I want there. I have plenty of music right now though, so I don't think I would be using the Zune Pass (I've only done trials and a month here and there for the 3 years that I've had my Zune 30). Tough decision.
EDIT- Ordered it. I've been hyped about the Zune HD for months now, but the Touch is honestly a better product, and it's cheaper at the moment. No tax and free 2 day shipping along with the $20 off made it so that I couldn't resist it. There's a good chance I'll get a Zune HD if I see it for around $150, but I'll just stick with the Zune 30 for the gym (FM radio), mowing, etc. The iPod Touch is definitely what I need at school though.
