How often do you upgrade your other passions?

Here in audio-land, we read about the hot new amp or CD player and we think, "geez, I've got to find a way to get that." Or, the upgraded version of what we've currently got comes out, and loving what we have, we really have to have the new improved version.

How about other hobbies / passions? How quickly do you upgrade to the new watch model, the new bike, the new car? Are we semi-unique here in audio-land, or merely a pattern that exists everywhere?
