My Sharp Zaurus SL-C3100 is arguably the best gadget I ever purchased. You can look up the history here if interested as it was a device far ahead of its time.
Every so often I bust the Z back out because someone has done something amazing that I need to try.
This is one of those times.
I keep in touch with a handful of users from "the old days". It was about nine months ago I helped compile apps on my Z for OpenBSD 5.6 beta. One person from that group shot me an email saying there was an attempt at getting ArchLinux running and I needed to be in on it.
An hour later I had a working ArchLinuxARM system running on my Z, including network card. I can't explain how great it is to have a current OS running on 10 year old hardware.
Continued development is ongoing as device specific issues are now being addressed to hopefully get more graphical software functional.
