Well, considering the recent news, I think it's time to publish something I did long ago: running webOS 1 on the N900. http://www.youtube.com/watch?v=XbYX0-5fddM While usable, it was a bit on the slow side (webOS is 320x480x32 while the N900 is 800x480x16 so there was scaling and color conversion), and NDK apps didn't work. And the method I used will not work for more recent versions. But still doable.
