Illume on Treo 650
Carsten Haitzler (The Rasterman) has been playing with Linux on the Treo 650 as well. See his blog for a video and (expert level) instructions on running Illume (an Enlightenment module for mobile devices) on the Treo 650 and Neo Freerunner. Illume seems to run incredibly well given the Treo's meager specs. This is excellent as it looks like we will be able to run something very similar to the software stack used on the Freerunner.
