USB 2.0 is way cooler then the previous version as it could run up to 480MBps. However, that is going to be smashed through soon due to the release of the USB 3.0 standard. This new standard will be capable of transfer speeds up to 4.8Gbps which is a HUGE leap of 10 times. The 3.0 specification should be with us early this year with products arriving in 2009 - 2010. USB 3.0 will be backwards compatible with 2.0 and 1.1. Also it will feature some more efficient protocols which will shut down to preserve power when not in use. The cables will be parallel optical which allows for the higher speeds. Bring it on!
