I'm going to buy one for sure. I'm not quite sure what I'd use it for yet. I'm interested to see what kind of driver support exists on the ARM version of Debian/Fedora for things like this:

A low power, wireless Linux box just a tad larger than an Altoids tin for under $50 is quite interesting for a number of reasons.
I'm also curious to see what these kind of devices mean for piracy. A standard SD card can hold up to 32GB of data. That's quite a bit. You've got a $50 server that is going to be impossible to track, and it can run on batteries. You could reinvent the street vendor who sells bootleg DVDs on the corner. You just name your AP something like "GET NEW MOVIES FOR $1"
