If you can get through all the ads, Futurelooks has a good review up on the Zune 80.

Microsoft still has some work to do, but they've made huge strides with the Zune 80GB, especially when compared to the brown brick known as the Zune 30GB. For starters, they might want to offer the Zune 80GB in colors other than black (the red was discontinued after Valentines Day 2008).

Pros
* Much improved menu interface
* Zune Pad is a huge leap in the right direction
* Streamlined audio and video podcast support
* Wireless synchronization capability
* Great set of premium earphones

Cons
* Still too large for my tastes, Zune 4/8GB might be better
* Muted colors while watching videos, only QVGA resolution
* Crippled Wi-Fi capabilities; wheres web surfing and Internet radio?
* Less than stellar battery life
* No AC/DC power adapter included

Now, I can live with some of the cons. I have no true arguments with them, but what the heck is he smoking? Less than stellar battery life? Huh? No, it falls short to the iPod Classic by a few hours, but 20+ hours on a hard drive based player, especially with the huge screen, *is stellar. Less than stellar... LOL
