Oh, I am SO with you on the idea of more support for other platforms. I'd really like to see ink recognition for the Tablet PC. The tablets are gaining ground in the U.S.A. Of course, if GE came out for the MAC, I might even buy a cheap MAC and I would REALLY love to see PalmOS support as well...
Realistically, I know how tough it is to develop for even a single platform. Palm as well as Mac are quite different environments from Windows. I haven't seen many tools for everything unless you go with C and learn the machine hardware!
Maybe another way to go for GE would be to develop single applications for each platform and sell them separately. ie: GE-Mac, GE-Windows, GE-Palm.
Alas, again, Makslane is definately a world talented programmer, but he is just one person. Accomplishing the support for all of the platforms that are already included in GE is an amazing accomplishment in and of itself. It is a lot to expect that one person program for all platforms.
