I had the S90, but I sold it as soon as the S100 was announced and got 12'000 yen which was pretty good going I thought, I'd used it for 18months and got it for about 28'000 yen to start with.
I borrowed my friends S95 for a trip to Kyoto recently as I didn't want to carry too much gear. I also took my 5DmkII and 50mm f1.2L and my Mamiya 7II, but 85% ofthe time I was happy to just take pics with the S95 for fun.
