i've been messing around with it a little today
being completely inept at this sort of thing i failed miserably at getting either the html or flash programs to run, but i did get the kernel to load and a desktop to appear with a few programs running.
tbh, theres not really much that needs to be improved in terms of GUI or usability, the biggest hurdle is going to be getting the whole thing to a point where a complete newbie can download a .zpk of linux and then be able to launch it like they would anything else.
as the flash player and html viewer are completed i believe we will be presented with a highly competent alternative to wind-ups with an even greater selection of programs. i'm confident that the devs will come up with text editor, pdf viewer, image software, web browser, flash player and a myriad of other things that can be used on the gp32
