I touched a Zune for the first time yesterday. The first thing I tried to do was use the "scrollwheel", before realizing that they were just four buttons. That's a design flaw: don't mislead users about using the interface. If they are just buttons, make sure I notice that at a glance.
Unfortunately, there were no other Zunes around, so I couldn't try the infamous squirting feature. I imagine this will often be the case in real life usage as well.
I have mixed feelings about the Zune coverage and reviews. One on hand, as an Apple shareholder, I'm glad to see that the much hyped Zune is no threat to iPod. However, I also feel a little sorry for the Zune team at Microsoft. There are a lot of people who I'm sure put a lot of hard work into making this a reality, only to have it ridiculed in nearly every review. Although, what did they expect by making it incompatible with PlaysForSure and requiring users to buy Zune points?
This is just another example where Apple Gets It™ and Microsoft is too tied to their special interests.
