I have to say, it's been a Sony strength for many many years, and they've kept up the tradition with the PS3.
The Blu-ray controller has to be the best remote I've used / owned in a long time. Not only is the bluetooth transmission superb, the layout and the feel are just right and it happily sits alongside my more 'esoteric' controllers.
Just had to say that. Actually having said that, the PS3 is a superbly made piece of equipment as it is. It certainly feels super solid and looks the part. Again it sits convincingly alongside my more 'hi-fi-esque' components and doesn't look too out of place.
Nice to see that some mainstream electronics companies put some thought into their work.
