Well, I'm shocked myself, but I'll offer a contrary view. I have really looked forward to the E2, considering it as close to my perfect everyday light as I could think of. And don't get me wrong, I love it. I carry it whenever I have a jacket pocket to slip into, or on weekends in my jeans pocket.
But at work, which I'm at 40++ hours a week, the E2 is a bit awkward looking in jeans pockets and uncomfortable in Dockers. I like to carry a light at work in my pants pockets, having been caught in rolling blackouts before. Anyway, all told, the hours I carry my E1 is definitely more than the hours I carry the E2. In fact, having realized that, my highest-priority wish for SureFire is the 30 lumen E1 light.
The E2 is awesome, but the E1 can be carried in a watch pocket or comfortably in Dockers, so it's got an edge for me.
