I wonder ... if used with these 'kit' lenses ... who would still opt for the bulcky DSLR ?
Not me.
Oh, there are plenty of reasons for an amateur to go with the traditional DSLR's; image quality is still better, the form factor and controls have a browse appeal, lens availability is far and away better than what we get with m4/3, and it's quite frankly cheaper to go with Canikon in a lot of respects (there's no sub-$250 lens for m43 is there? Both Canon & Nikon offer several very good lenses I'm that price range). For pro's, don't get me started.
I made the same choice you did, stefaan, because the image quality was good enough and because I was and am willing to pay a premium to be able to carry 50-67% less weight (for a like-for-like kit) but let's not get carried away.
