I've been using Fluxbox in my set up, taking a tip from timekiller.org I added the bbbutton app for a while to relaunch things if they died or i accidentally closed them. that worked pretty well! I also used it to launch an on screen keyboard such as xkbd 'xkbd -geometry 1024x200+0+568' or xstroke to use the touch screen for gesture recognition
I also had taken advantage of the ~/.fluxbox/startup file to launch all types of apps [and scripts] when fluxbox booted, such as nGhost. I found this much easier than dealing with the rc/init scripts
I also used the ~/.fluxbox/keys file to create keyboard shortcuts/'macros' to do things [such as stop/start/restart wifi/bluetooth/phone] this got difficult to use once i gave up a keyboard/keypad and really was the catalyst for looking into new WMs. For a while i used xstroke to "draw" the keystrokes i wanted which also worked well but got old.
I'd like to try Matchbox WM after reading the IGo 8 Running on 'NIX thread and seeing dinuxlt's set up. Also Kev000 suggested a combination of "maximus+compiz" that looks promising and I hope he'll comment on it at some point.
I know my post is lacking the config's and screenshots I suggested but i promise I'll post them soon after I unpack my carputer from my recent move.
