I buy a used Nikon D40 as a backup for the D200, and I drown my Powershot A620 for the first time. It revives. I also supplement the lens lineup with the neat 10.5mm f/2.8 fisheye.
I now possess two Nikon SB800 flashes and am becoming quite a fan of off camera flash.
I'm diagnosed with MS, which changes my life dramatically - and also has a huge impact on my photography.
