An MP3 player is one of the most popular Christmas gifts for young and old alike, and is sure to brighten even the most sullen of faces on Christmas morning. But with so much choice available on the market, which do you choose for your special someone?

Apple's iPod dominates the market, but there are a number of other digital audio players to choose from that offer similar functions; in some cases, these cost a fraction of the price.

Finally, it's worth considering how much a player will be used to watch video - some of the devices here have larger screens than others. For Best Buy products in six great categories, visit PC Advisor's Christmas 2008 Buyers' Guide.
