I love dyno lighting systems for the "forget about it" factor. I also own a DiNotte battery set. They have different characteristics for different uses. You can't easily swap dyno-powered lights between bikes.
My "around town" bike used to use cheap AAA powered lights. I didn't have a backup, but I was never far from home either. If I'm riding distance at night with dyno-powered lights, I'll either have a battery light also, or carry a flashlight. That's handy for any bike repair.
