buy nex-5 or Olympus E-PL2

if you were in the market again, would you take the Olympus E-PL2 just announced over the nex-5?

Say IQ, compactness, ease of manual control, versatility (sunny landscapes to low light intimates), lens quality and availability (including both using adaptors and the included kit bundles--assume buying both e-mount kit lenses) were are high priorities.

Also how important is this fact to you: 4-stops of in-body IS in every old prime lense you ever shoot with vs. the sony IS kit zoom 18-55mm.

Thanks!
