ahahha.. tempting leh??
actually the g3 was a SERIOUS contender for me, but the 5mp and 8x
o-zoom of the cp5700 threw me over. if u're not after SUPER high
end, then the G3 is more than sufficient, a fast camera in terms of
lens speed, storage times and start-up times.
and if u ask me, canon is more user friendly, as in the controls
and functions. nikon is known to have a pretty steep learning
curve.
BUT.. i still can't get over the 8x zoom and 5mp on a nikon!!!!!!
and it's way way more chio looking than the G3!!
