The long awaited iTunes phone, the Motorola ROKR, is a flop. In fact, according to this article, at a Engadget reader meet-up in San Francisco the device was booed when the Engadget editors held up the ROKR as a door prize!
While the ROKR apparently sounds great many of the features were poorly implemented such as needing to use a USB 1.0 cable to transfer music to the phone (at very un-whopping transfer speeds up to 12MB/s). Also, the phone should be able to connect to the iTunes server and download the music directly without needing a PC. Finally, why the hard limit of 100 songs?
