My cousin and sometimes camping buddy gave me a Petzl Tikka LED headlamp for Christmas. Prior to actually using one I was never impressed with headlamps, but now I am becomming a convert. I EDC it in the pocket of my winter jacket. It is very handy for walking around in the dark and performing close-up tasks. Its great to have the light right where you need it and both hands free.

However, I found there are things that a handheld light does do better, like aiming it at something/someone before you turn it on. Or when there is fog/rain/snow in the air it is better for your line-of-site to be on a different axis than the beam of light - with the light on your head you are forced to look through the illuminated column of light.
