As powerful devices get more and more mainstream I find they are taking over the PIM type functions that have historically fallen to the PDA realm. People don't buy the expensive Sony U or OQO to do PIM functions, the expense doesn't make sense for that. But they are buying these UPCs to do their real computing tasks and since they also do PDA type functions very well they are supplanting the PDA with these devices.
You're right though, MS never seems to promote their stuff very well. I guess that's OUR job.
