It addresses many of the shortcomings of its predecessor (which I have in my pocket).
It has USB2.0 for fast data transfer speeds, A2DP for stereo Bluetooth, mini-SD card slot (2GB instead of 512MB), a 3.5mm headset jack (no adaptors) and more.
Mr. Wiz. - It's interesting that you bash the ROKR for having 512MB of memory while the W600i you are using only has 256MB internal with no expandable card.
