Guitar Port

Here’s a gadget that seems cool, but could be crappy. Line 6 GuitarPort lets you plug your electric guitar into your PC through a “retro” looking red box (it’s the Retro-ness of this thing that’s worrying me). The box can immitate a whole bunch of different classic guitar amp sounds, and also allows you to connect to an online service that gives you the equivalent of guitar karaoke, as well as lessons etc. Anyone have any experience with one of these?
