As someone about to join that demographic, Heather, I have to say it's not about age as much as it is about willingness to try new things. And sometimes that's influenced by the school you're in. I work with a lot of teachers at their schools and teach an online class in educational technology for teachers, and I hear some of my teachers mention the age thing, but often we have other veterans in class who don't fit that mold and help set the record straight. I also have newbies that show a good bit of resistance to change, as well.
I encourage all of my teachers to embrace the idea of "tinkering" so well described by John Seely Brown in last year's PBS documentary about Digital Media. I had to teach myself it was o.k. to tinker, because I wasn't brought up that way. Maybe that has more to do with it than age. I'm more willing to try new things with technology--now, and it sounds like you are, too. Enjoy your new position!
