With the Christmas tree chopped up and the New Year's resolutions made (and probably broken) the holidays are officially over and the new year has begun. But if you're on the receiving end of a gift from one of the 60% of Americans who purchased a gift card as a present this year, the Christmas season may not be quite over. Now you need to decide what to do with those gift cards and they probably won't be to a place like Newegg where you can geek-out on exotic hardware; instead you're shopping retail.

So what do you do with those gift cards before they begin to self-deduct? If you're thinking of an MP3 player, then you're in the right place. We're re-launching our coverage of MP3 players here at AnandTech, and to start things off we have a roundup of high-end MP3 players from juggernauts Apple and Microsoft, who between the two control the vast majority of the high-end high-margin market for MP3 players in the United States.

Apple of course needs no introduction in the MP3 player market, as while they were originally a couple of years late to the game they have managed to become the unlikely 800lb gorilla in the MP3 player market. iPod has very nearly become synonymous with "MP3 player" in common vernacular, a short-but-succinct summary of Apple's dominance (and a possible trademark nightmare for the company in the future). They're the company to beat, they have no desire to hide this, and they have no intention of letting it happen.

Meanwhile we also have Microsoft, a far newer competitor that has done surprisingly well or surprisingly poor in the market so far, depending on who you ask. Their first Zune was panned by critics for various perceived inadequacies and the Zune did not dislodge Apple from being the king of the hill as Microsoft had hoped. Yet on the other hand, the first Zune was enough to catapult Microsoft to the #2 supplier of hard drive based MP3 players in the United States, shooting past entrenched players like Creative practically overnight. They came nowhere close to beating Apple in the MP3 player market, but they got closer than anyone else in recent years and are willing to throw the money and leverage that is Microsoft to try again and again.

It has been no accident that Microsoft has chosen the past year to break in to the MP3 player market. Issues of company diversification aside, as an established market the MP3 player market has in the past year finally matured. For Apple this is a troubling news, as they must now compete with themselves to sell new iPods since they can no longer bank on market growth to keep their sales high. Meanwhile for Microsoft this is great news, as Microsoft's is often at its best when it's time to compete in a mature market where breakthroughs are slow and the risk of competitors blind sighting them is low.

The MP3 players we will be looking at today represent the shifts in product styles that come with that maturation. From Apple we have the old guard and the new guard; the iPods Classic and Touch respectively. From Microsoft we have the Zune 80, a product that is both the old and new guards at the same time, striving to fix what ailed the first Zune in the process. How do these MP3 players stack up? Let's find out.
