if u go back to P&S it is all fair and good and show where your priorities are.
to me, when i got the e-pl1 it opened my eyes to the creative opportunities i had missed out with P&S, but then again i had some old OM lenses in a box, and that was what opened my eyes rather than the kit lens.
my advice to P&S people is that, unless you have consistently owned the top P&S stuff like Canon G and S series etc, and found yourself limited and considering SLR... don't bother.
(a) there is a steep learning curve involved that you have to enjoy
(b) there is additional investment required in lenses, like with every modular system
only then will you draw the full benefits.
by the way, these days, even $100 P&S are quite capable. i have invested a lot into m43, but i own a Canon S90 i love and even an A3100 that simply lies around... and takes good pictures and goes for $99 these days. for an easy shot i probably would not care much about the difference between the A3100 and my E-PL2 with the CV 25:0.95 lens on it...
