The sad thing is I had a C compiler + UI designer for my ancient Palm device as a kid years ago, and the very simple Palm event loop (as best as I can remember) made development quite easy.
Fascinating find, thanks! I miss the "new" feeling of technology prevalent with Palm. We seem to have settled into gaudy client/server apps, where the control/power is in the hands of the server.
