I've read all the threads about the Xtar S1, but it doesn't sound like there are very many people who actually have one.
For those of you who do have one, what do you think about the light? No need to duplicate the technical information in the various reviews; I'm interested in hearing how you like it or dislike it, what you use it for, what you wish would be different, etc.
For those of you who like the light but didn't get one, why? What would make you buy it?
