I feel it's pretty easy to keep up with new technologies when necessary, since I don't have to relearn the basics and almost always have a reference point as in "oh X is similar to what we used to call Y in Z".
One huge shift for me is distribution - as the browser is now almost capable as a general UI it's easier to not worry about OSes, installers, versioning, etc. This is true even for people who primarily don't work on web apps.
