All -- someone locally is offering an X100, with case, accessories and original packaging, for $450. At first I thought it's a great deal, but -- isn't the X100S a significant improvement? And regardless, we're talking about a camera with a fixed 35mm equivalent lens, right? Limited utility.
Very sorry if it sounds like I've just climbed out from under a rock.
Of course the 100s and t offer more! More features, more speed (as it seems), more pixels..... for those who need it. I was VERY happy with my X100, in fact so happy I grabbed one on the Bay again just now (is in the mail right now).
If you want very good picture quality, a camera that's nice to hold and operate, that works just like the cameras of the olde times, then a good, used X100 is the cheapest offer.
Don't let the fixed lens put you off! It helped me concentrate on the essential, taking pictures and seeing the world with new eyes. Didn't really feel the limitations.
My favourite cameras are the Oly XA, XA2 and Trip 35 which all have fixed lenses, and the OM2n I mainly use with the 28mm. I don't like changing lenses when I'm out and about, which is the reason I dropped the DSLR gear 3 years ago. Never looked back. I made an error trying to get into the X-E1 and Fuji's XF lenses recently, but that was too much like lugging the heavy DSLR bad again. I'll keep the X-E1 to use with my old glass and a Skink pinhole and that's it.
The X100 will again be my daily carry.... well until GAS hits again!
Now if you are a 'notorious lens changer', it's not a camera for you.
