Because, for me anyways, it's a hobby. So, I buy something new; tinker with it maybe, shoot it at the range, kill something with it and move it along in the Classifieds.
I do the exact same with scopes, binos, etc.
Bow fanatics are hardcore. They buy a new model every year chasing perfection.
If I wasn't married, I'd be buying a new bow yearly for sure. I would rather bow hunt than gun hunt. The wife can't stand me talking about buying a new bow, but guns she could care less. I'm probably averaging a new bow every 6 years at this point. Of course I went several years with no bow while still on AD and moving every 3-4 years.
