The Motorola Rokr E1 is a Motorola mobile phone developed in partnership with iTunes to make the downloading and playing of MP3’s easy for a phone user. Makes sense, no separate player required and you’ll never miss a call because you were listening to your iPod.
The problem most reviewers have (here’s one Motorola Rokr E1 review) is that it only holds 100 songs ! That’s around 9 albums. I’m just getting into MP3 on the move and the idea appeals to me, but let’s face it, if you’re going to pay for this kind of mobile phone technology you better be able to store your entire CD collection on it.
