I think that maybe, just maybe, some people are getting a little bit overwrought with regards their dislike of the good old Imperial measurements system. The most esoteric bits are no longer in common use, and the rest isn't that hard to comprehend. I was raised in a metric country, but have no real trouble with the common Imperial measures. It's simply a matter of familiarity and use. It's really not that big a deal. For the record, I'm 55.
(Even Whitworth isn't that hard to understand, it just takes a bit of effort and a desire to learn. And perhaps, an interest in manky old Brit machinery helps too.)
Of more concern to me (and getting somewhat back on topic) - when are we going to finally get a 1/24 injection kit of the RA23 Toyota Celica coupe so that I can build a model of my first and most favourite car? Aoshima, are you listening?
