Debian Lenny
I'm thinking of doing an installation of Debian Lenny, aka Testing. I already have a CD of the business-card ISO. I got it from here.
I'm generally a big proponent of using Etch, the current stable version of Debian, but Debian Testing is supposed to be as stable, if not more so, than Ubuntu.
One thing Ubuntu 7.04 and 7.10 do is handle my Alps touchpad better than Debian Etch. Anyhow, I have a drive for the Maxspeed Maxterm converted thin client that has Debian Etch with Xfce on it. I just might wipe it and put Debian Lenny on it. Last time I installed Lenny, I think I encrypted the entire drive. Might do that again, too.
