I personally would like to see a Linux based offering. While I am most used to the Garnet version of PalmOS, and it has served me well with
my current Treo-only computing solution, I do feel that there can be more done and hopefully more streamlined like the PalmOS but capable as the WM platform is.
I have been under the assumption since early last year that a Linux offering by Palm apart from PalmSource/Access is not far off. I personally think that time is a lot closer than it is far, just not for Treos.
