I try to keep gadgetry away from a few parts of my life. I use a completely manual telescope despite most people wanting GPS enabled computer driven scopes. Similarly, on the bike, I have a simple wired comp and lighting in the winter. I do ride with one or two video cams, but that's more along the line of safety gear, I don't really count them.
I've found that in some things, gadgetry just detracts from the experience.
