Legroom is important to me, but rarely has there been insufficient legroom in the premium cabin. However, there are larger differences between the airlines in terms of seat comfort/features.

I expect to see much better catering when I fly in F. I will definitely not be pleased if some sort of light meal is not offered on a flight over an hour in length. I'll often take a glass of wine, but it doesn't have to be an expensive brand...just palatable. Good coffee is also important.

In-flight entertainment has never been a huge priority for me, although I appreciate the newer options, such as mini-DVD players and "live satellite TV." I usually don't like the main screen feature and/or, the screen is too far away/too small. Some PTVs are also too small, and many only offer a few channels.

I agree with Punki about ambiance, at least in the sense that the cabin needs to be clean and attractive. Obviously, with so many people travelling on upgrades, you can't expect too much from your fellow passengers, but I think the F/As should try to offer more professional service up front.
