It's only workbench that runs in 800x600 setting as you need the monitor settings to make it work. It certainly makes navigating though larger folders easier as you can really open the windows to see more stuff. I have the links laying around to a german forum with the superdrive(think it's called that) and the latest firmware. It however does eat memory if you have fancy workbench effects going. So I use the oldschool wb 1.3 theme on ClassicWB full as it looks good and keeps things zipping along. 
As for the device it's self. It does an adequate job. I have no reason to complain for what I use it for.
Thanks. I really like your A600 setup. Looks like a nice, compact, yet powerful system.
Jens still has some 42MHz accelerators for the 1200 that also look attractive (if he ever gets around to finishing the latest flicker fixer for that machine).
Hey, that's not too social, is it?
