Hey rizla, that top five is based on reviews on
www.reevoo.com. They have over 50 online retail partners and whenever somebody buys something through one of the partners, they're sent a questionnaire about the product. The only people who can leave reviews are those people who have bought the product so you know that the reviews are all genuine. They're the only review site that do that and they're partnered with big players like Comet, Dixons, Currys, Empire Direct etc.
I sorted all of the mp3s into ratings order but you can order them by the "most viewed":
http://www.reevoo.com/browse/product_type/mp3_players?order=most_viewed . That does show a definite Apple dominance. There are a lot more people interested in iPods and we know that a lot of people buy them, everyone is caught up in the Apple frenzy at the mo. What interested me was the ratings people gave them and what they complained about.
