Java apps for cellphones need to be signed to get access to certain onboard services. Last I checked this costs on the order of 500USD/year and I doubt that it involves any actual tests.
Even the owner of the phone can't sign applications which he himself wrote and wants to install on his own device. Eg on my Nokia 6230i I can allow my apps to access the memory card, but only after closing a dialog at each read/write-attempt. Only a signed application has unlimited read/write access, etc.
Due to the 2 fast USB2 ports and the ability to run Linux, this device is well suited for interface projects, eg. connecting any USB device to the internet. See my project about WLAN-interfaces for digital cameras, which uses the Linksys NSLU2 running Unslung-Linux (Kernel 2.4), gphoto and some scripts. It allows you to wirelessly operate almost any digital camera via Web-interface: http://www.fh-furtwangen.de/~dersch/gphoto/remote. html I have used the device to connect my Palm Tungsten and printers to the internet, there are more projects, see the yahoo-group.
In theory, a desktop device could be set up using a USB-VGA adapter and USB-connected keyboard+mouse. I have actually done that and ported the necessary VGA-drivers to Linux 2.4, see http://www.fh-furtwangen.de/~dersch/. However, this will (a) increase cost considerably (more like 350USD/EUR), and (b) you end up with a 133/266MHz, 32 MB system, which is nowhere as powerful as eg. a Mac mini (and still lacks CD/DVD-drive).

The Zeppelin NT is purchased from "ZLT Zeppelin Luftschifftechnik GmbH" and the 4th they are building, see this link (german)
