While not following the rest of the thread, I find your question interesting.
I'm not that familiar with this piece of Jens' hardware.
How well does it work and what software is compatible with the 800x600 display?
At one time I ran PCs at this setting and it was adequate.
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.
