On that count: I think there are many older flashlights out there that could do that job *and* offer access to settings ... but I'd say that the Moon Tiny Flash sure does look the part and - should you have the appropriate knowledge, as Hamish himself points out - can walk the walk, too. I'm just not sure it's what the market wants or needs; the Q20II, on the other hand, was and is a breath of fresh air - add a couple of extra triggers and/or receivers, and you can really do quite a lot with that tiny system and some additional inexpensive lights.
Just to add to the list of useful little flashlights: I don't think you can still buy it new, but I really appreciate what the Metz 34 CS-2 digital brings to the table - it's really impressively small for such a powerful light, you can use it as a secondary light (two modes to trigger it with other flashlights - no real wirelss), and it does pack a punch if you need it, as well as quite comprehensive auto modes, though no direct manual control, but it's close ... It's hardly any bigger than the Q20II, too. So, between those two little lights, you can already do a whole lot of interesting things ... A rather weak, fixed power small flash, while nice, just isn't that much of an asset ...
(I had to figure out how to switch off exposure simulation on the Z 50 to be able to use it with manual flash ... man, that was annoying ... Okay, I admit most of it was pilote error, but ... stuff like this just works on DSLRs - and even my Leicas ...)
