Zonbu Laptop: Good deal on Linux Laptop and Mini Desktop

As I was researching information on my Asus Eee pricing post , I came across an ad for Zonbu. I at first believed it to be another Linux distro...then I saw the add above.

$279 for a Linux laptop similar to the Asus Eee for that cheap! Whats the catch I said.

I am not sure if it is a catch, but the site keeps referring to a "no hassle maintenance package" of sorts.

The package includes back ups, updates, support, etc. for $15 / month. I hope it is not a requirement, that would definitely add to the overall cost of this thing.

They also offer a mini desktop for $99. Below are the specs on it.
