Some people are amused by making old tech do new things. I am one of them. Much more entertaining (and educational) than whipping out a credit card for the latest i-thing; any schmo can do that.

There are still sites that have software for the old Palms, though you need to dig a little deeper these days. (I'm involved in one such site, and there are still new people registering and commenting on their "new" toys.)

I would not be surprised if there are enthusiasts still chatting about your Dell. These people know where to find software too.
