The previous thread, whilst interesting, was perhaps not a fair comparison of the two machines, as the S1 photo has been manipulated with auto levels. So I now have three shots with which to compare:

http://www.flightasia.com/bbj_sin_s1raw.jpg (shot with S1, only resized and sharpened)
http://www.flightasia.com/bbj_sin2.jpg (shot with S1, resized, sharpened and auto levels applied)
Interesting to see that even when not changing the raw image, there are clear diffrerences in the output from both cameras. Both both are still pleasing.
Full frame always beats post processing
