The Zune has gotten it's first few reviews, and I have to say, I was impressed that it took up a large chunk of this week's MacBreak Weekly where the guys (all Apple fanboys) gave it pretty much nothing but accolades! Not only that, but it made me want to buy one (well, if I had cash put into my hand of course, not with real money). Andy Ihnatko's review is similar (Andy is on MacBreak Weekly if you didn't know).
Not all are impressed though. The apps that are available with it come with pre-roll ads which would f-ing infuriate me. I know they're free apps, but at launch having to sit through a 20-30 second full screen video ad? No thanks. Even the free apps on the Apple App store are either small banner ads or splash screens. 20 seconds isn't long in the grand scheme of things, but check the videos to see just how crazy it would make you to have to sit through them.
That said, it's a 1.0 product from Microsoft, I have no doubts their App and store experience will get better.
