Nah, I used to play a grand piano in the marching band. Part of my aerobics program.

I guess it depends on what you want to do with them. In the past when I went to different places it was nice to have a portable keyboard with me since the pianos that were avaialable were not in the best of shape (read good for boat anchors). But even with all the beatings from putting the keyboards in and out of the car it still was fine.
