I measured the and the minolta dimage x20 and the slightly newer (same cam really) x21 optio pentax 33lf and and the minolta is half the weight and much thinner as well as being tiny in general.
I couldnt tell the difference in picture quality between my dads old fuji and more recent cannon ixus2 3.2 so that show how much i now about digital cameras i suppose
I'l have to go and have an extensive play in the shops and decide then.
