I am stuck on the fact that I see lot's of old Palm apps that did a variety of things on what is supposed to be a more archaic platform. Why?

I suspect it is the root drawback of the "open platform": there is no reward for spending energy and time if the end product is given away for free!

I think this is where the iphone and Android platforms have got it going on with the "freemium" model.

Now, if this is NOT the case, I would really like to hear more as to why not...

And thanks again for all of your input here in this community. It is valuable!
