Just curious... what's wrong with Linpus? I've downloaded it and intended to play with it a bit.
Well after some hours of playing with linpus I have to say it does its job pretty well. Everything I tested so far works out of the box, but there are some things that can't be done (easily) with the default configuration. For example:
Autologin: when you boot AAone for the first time, it asks you a password, without being informed if it's the admin (root) or your regular password. You set a password, and then discover you hardly ever need it, because you only have 1 user (named 'user', oh duh) and it usually boots automatically to the desktop (xfce with a really user friendly interface).
No menus, there are only icons in the desktop, so if you install any new app, you cannot get it (unless you use a 'trick').
When I wanted to get a terminal, I searched for an icon called "terminal" and I couldn't find it. It's just not there.
"Ctrl-Alt-F1 Can't fail", I thought... but it did nothing

. then I tried Alt-f2 and a launcher popped up. Then everything was straight: Alt-f2, xterm, return. Whoaw, at least I have a terminal there, with bash

.
Vim is there, and the usual directory tree. yum (I don't know if it's a trimmed down yum or full fledged one). Then I had access to /etc/inittab, and I can spawn terminals at boot (to save files in /etc/ , I had to be root, so I had to sudo su , and no password was asked) .
gdm is there to manage users, but it's a bit hidden, and had to edit /etc/rc.d/rc.S changing the xinit line to gdm (can't remember paths).
Now I get gdm, with user 'user' and expecting a pass. So far so good.
I installed ratpoison wm using yum, and it appeared in my sessions menu (gdm), but when I entered, I discovered wireless is managed after booting into xfce... so I guess I'll have to write a script to manage wireless on 'other' wm's.
That's only my 20h experience, but I think I can make AAone fit my needs better if I have an unlocked OS to tweak. However. linpus does exactly what it's meant for, but I'm not a standard user I guess... compiling, ssh, perl...
I imagine AAone with WinXP will give users the chance to install new software. There's no way to do it easily in linpus (AFAIK)
Ah, there's no /etc/shadow there, everything is in /etc/passwd

I'll keep you informed
