I'm pretty serious about photography and not only don't have a GR, I actually had one for a month and actually rejected it - HORRORS! - in favor of what I saw (and still see) as a better alternative for me. I have two cameras small enough to carry all the time but I don't carry either all the time because that's not how I shoot. I'm out shooting or I'm not - I don't want to always have a camera with me because that means I'm always on the lookout for photographic opportunities and that's not the way my brain and photography work best together.
Being primarily a Nikon DSLR shooter now, I hang out on a couple of Nikon DSLR specific forums and people are always making statements like that over there too, even to the point of saying it about one one particular Nikon DSLR over another! Which is obviously BS of the highest order, but no more than it is when used here about the GR.
If Ricoh comes out with a new GR and improves a couple of features to make it more to my liking, I'll take a good look at it and consider buying it - but I sure won't make any absolute statements about any camera that doesn't exist yet...
I'm sure Louis meant no offense and was just being enthusiastic about his camera, but I agree with Nic that ultimately statements like that are just pure brand loyalty and insulting to those with other preferences even if not remotely intended that way.
Oh, and by the way, REAL photographers use an OVF - who wants to see the world through a little TV set!
(and no, of course I don't believe this - just another of this type of statement I run into all the time)
