Its a complete joke that all the zealots are bitching just becasue the thing is 'slightly bigger' than an iPod. I guess none of them realised that throughout most of the iPods reign - it has been significantly bigger than competetive products, which just happens to have slightly improved recently.
What were you saying at the time cheap korean makers were bringing out smaller products with more functionality? Jack shit of course. You all thought the size was negligable, but now the opposite.
The original case laid down by the bigger/fatter/less-functional iPod was clear, that the product doesnt have to be smaller to be better - how many people bought otherwise because of this? Exactly, it was probably some kind of obscure anomoly. So please, the success of the iPod is not-at-all down to the size, thats a minor point. On all other points - such as functionality people might actually care about, product identity, marketing, and integration are all trumped by Microsoft here, they understand what made the iPod a success, and they are building a strong first generation product on those factors.
Infact if you read what the managers behind the thing say, they arent at all pitched against the iPod, they believe there are new markets to be had. They also say they would like a super slim minute 100gb player in the future, but they'll obviously cross that bridge when they come to it.
