When I try to explain to my wife (boss) that I 'need' the SD1M; she will ask (quite legitimately too!!) - why do you need a new camera when you got one (SD15) less than 2 years ago? She won't understand or be interested in higher resolution and better construction! Praising her brown bread (Ed) won't work as she doesn't make it anymore since she went back to work - I have to buy it now!! I did sell an SD14 to my brother so I only have one DSLR now -so maybe that's the angle I'll work one - needing two cameras in case one breaks!!
