That's actually quite important. No point getting a camera you don't like to use.i'm quite firm on getting a nikon. personally i think i would prefer the layout of the buttons that way.
plus, i'm the kind once i've decided on a brand, if i were to be persuaded to get other brands, i might end up being unhappy because it wasn't my original choice to start with.
you may say i'm being a brand-conscious freak but i think the brand boils down to comfort of using the camera for me. HAHA.
