Ahh, but Don - your stuff is actually pretty useful and practical. Most of what qualifies as 'chindogu', you wouldn't want to be caught dead with in public.
Take your M6 setup, for example. I could see most of the CPF members walking around with that, if they had M6s to put in it. Heck, most of 'em would probably walk around with it even if they didn't have the M6..
However, there is probably a lot of borderline chindogu which the general public wouldn't give a second thought to, but which gadget freaks like me jump all over..
