I bet Mapsource would still work with a newer GPS. You just would not be able to take advantage of some of those "new features" that Tom mentions are in Basecamp. But, if you are using an "obsolete" GPS (like I am with my zumo 550's) then the new features in Basecamp don't work with the old GPS anyway, so sticking with Mapsource is fine.
The one big reason I'd like to learn to get used to Basecamp is that that Mapsource, in it's later incarnations, has a propensity for crashing in the middle of planning a large route. I've gotten used to saving my work often while using Mapsource so I won't lose too much if/when it does crash, but unfortunately that (those?) bugs will never get fixed by Garmin.
I have Ed's tutorial, and I have mucked around with Basecamp enough to know that, for mow, it is easier for me to just put up with Mapsource's crashing than learn the new program.
