Sony rewards had my unit arrive Friday and I had it installed in about 5 mins.
Was dissappointed in the dumbed down remote control compared to the S350 and S550. This new one is half the size and does NOT include Eject, Mute or backlighting. Why no 1GB memory stick this time Sony, that was included in both of my S350 and S550 BD players??

Also, the PQ for blu-ray seems to be on par with the S550, though I can't tell a difference with the audio between the two, connected to my Samsung thru HMDI. Waiting for Sony's DN1000 for my audio needs.
I have yet to try any SD DVD's in the new unit, so not sure yet how well they compare there.
