Had mine since April. The SL-6000 is a fun (not so little) machine. I had one guy ask if it was an "older" machine because of its size. Once I told him I was running a Web server and a VNCserver, I got a little more respect.
Thanks to DevImg, I have even done a little compiling on the Z. It isn't fast, but it does work! I am very fond of a wireless signal strength monitoring tool called wavemon. It is just a terminal based program, but it reads signal strenght in DB (which is more precise). Because it runs in a terminal, I can ssh into the Z (from my laptop) run wavemon, and monitor the signal strength that the Z is seeing. Then I just have my son wander around the house, while I do the wlan site survey from the comfort of my easy chair ;-)
It is too bad that Sharp is pulling the SL-6000 out of the US market. But that isn't the end of the world. After all, I live in Canada (where they are _not_ sold) and I still have one!
