Gumstix Computers

I have been checking out these very small expandable computers for a long time now and trying to figure out a cool application for them.

The only thing I can come up with so far that interests me is a network device.  The network device would plug into someones home network and act as a internet content filter.  That means it would scan and block out any unwanted web sites/links/images/emails and such on your home network as you use the internet.  There are even some add on boards that could make it a WiFi hotspot.  So the options in this are really rich.

Can you think of anything that a really small computer would be useful for?
