The main reason to complain is the 512MB memory, which can only hold about 100 songs:
The 100-song limit hasn’t been lifted with the new phone. The limited song capacity was a major factor that contributed to the relatively low sales figures for the ROKR, the first phone to include iTunes music released last September by Apple.Analysts believe it's unlikely the storage capacity will increase in the near future because iTunes phones with higher capacity could take away sales from the iPod nano and other iPod models.
The SLVR 7 also features a VGA camera and iss less than half an inch thick with a weigh of 3.5 ounces. It features a thinner, better looking design than the ROKR and retails for $199.
