<< Am I the only one thinking this way? >>
I would agree. I do EDC my U2 despite its size. Although a civilian I carry enough stuff on my belt already (pager, cell phone, leatherman, and a self defense item), so the U2 just naturally fits in. The wife thinks I am crazy and jokes about what I carry, but if something nasty happens each item is needed. I also do not consider the U2 as obsolete. It works well for me in output, beam profile, and battery life.
If a small sized light is needed I already have other alternatives, so purchasing another light "just because" really is not needed. None are as small as the NovaTac lights, but I do not need anything to be that small and powerful. Likewise, each light I select to carry on any individual day is based upon what I am going to be doing and what I think my needs will be. It may be the U2, an A2, a Huntlight Cree, or even a X5.
All that being said, everyone's needs and desires are different. There are folks who may need a very small profile light to keep it hidden (tucked away nicely in a suit) or because they already carry a lot more than I do (Think paramedic), or who just wanrt the latest and greatest. No harm in that. I am sure I will purchase more lights down the road if the need is there or the desire creeps in.
