The advantage of the L10 is it's flip screen... similar to E3.... They both uses the 4/3 system but Panasonic's anti shake is on the lens & not sensor. If I am not wrong beside Canon & Nikon's dslr system only Panasonic have it in the lens & not body... :dunno:
Even Panasonic themselves are not promoting very much on the dslr models (G1 is not a dslr).
