Great bit of kit
I have just got one of this set up and am very pleased with it, very easy to set up once you get the full set of instructions. I was using twonky before but the Philips SLA5520s were becoming difficuilt to turn on for some reason, and having the TV on to use the PS3 seemed a bit "over the top". The remote is easy to use, the screen is great and being able have the remote at hand where ever you are around the house is very usefull.
Twonky is still very good at displaying my digital pictures and videos through the PS3 but the Duet is the way to go with music.
