Wireless News Factor took a look at the ROKR E1 music phone from Motorola, here's a snip from their review:

Although it comes with a 512-MB microSD card, there is a 100-song limit on the Motorola Rokr, regardless of memory capacity. This leaves you with enough selection for a workout but not enough for longer trips. On the plus side, the included music earphones also double as a hands-free set..
