USB 2.0 is now out.  What is the difference with your current USB 1.1 port?  Speed – plain and simple.  Our research has shown that you do not get 40x the speed, as advertised.  At full bandwidth, the 2.0 ports are supposed to get 480 mbps, while the older 1.1 ports are supposed to get 12 mbps transfers.  The actual rates achieved are closer to 375 mbps.  This is still much faster than the older style ports.  If you are going to connect high speed devices such as digital cameras, external hard drives, CD-RW drives, etc.  then you will want to upgrade your computer to include a USB 2.0 port.  These new ports will still support all the 1.1 style devices as well.
