Debian 6.0.7 at 500Mhz, 256Mb
I had a little extra time today, so I did a ritual backup of my standard Arch Linux framebuffer system, and installed the full Gnome suite to the Solo.
The results were not as disappointing as you might have imagined.
Debian has always done a good job keeping the lid on Gnome’s grotesque proportions. The full desktop is floating on +/- 100Mb out of the 256Mb available, with just a tease of swap.
