Works great with netbooks
As you can see with our images below, it works great with the new netbooks that are available, like the Acer Aspire One.  It's great for using with wireless broadband adapters, thumbdrives, activation dongles, etc. 

Works great in tight spots
This USB 2.0 extension cable has been used mostly by portable users who don't want to have a lot of extra cables with them in a big bunch.  It's amazing how helpful short cables can be in your little portable computer bag!
