What’s better: digital or optical distortion correction? (dpreview)

Dpreview tried to found an answer to the following question: Can software ever take the place of optical excellence?

They tested four cameras: Canon Powershot S90, Panasonic Lumix DMC-LX3, Panasonic Lumix DMC-G1 and the Olympus E-PL1 } if ($loc == 'ES') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'IT') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'AT') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'DE') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'BE') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'AU') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'FR' OR $loc == 'FX') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'NL') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'CA') { $sel = "1"; ?>Olympus E-PL1 } if ($loc == 'US') { $sel = "1"; ?>Olympus E-PL1 } if ($sel != '1') {?>Olympus E-PL1 } ?>.

And what did they discover? “Purely optically-corrected design have an edge over the Micro Four Thirds lens that combines both optical and digital correction.”
Interesting!
