You have overestimated my power... I can't stop him from answering your question at all.
In any case, at the risk of being accused of being 'anally-specific' (surely there must be a less offensive word to use... unless you intended to be deliberately offensive at that) again, while the EX1 is a compact all-in-one camera, the GF2 or E-PL2 is not so 'all-in-one' as there are lenses that have to be carried along with them. And even if only the smallest prime lens is attached (severely limiting their versatility) and brought along, they are not really as pocketable as the EX1 or LX5 or XZ-1.
