Thanks for all the replies everyone, I should now be able to put together some kind of result.
I see that most of you put i-pod/ipod mini as there choice, yet still put down as the reason, because of features
...well, i would have just expected advertising thats all, because the popularity of it. Like all apple products.. the price seems to be higher than what you get.
Though this will help in my reseach as it suggests that they have put just enough features in to make it worthwhile (most are added seperatly) and will give me a player to research more deeply, adding from that.
As some of you answered ones that weren't listed, e.g. Triangle lol, *cough* Steven11 *cough* I might have to pretend this was something else, or just have it as a don't know
