I received the PC version as a Christmas gift. I rented the PS3 version for three days a week prior to Christmas and I absolutely hated it. The PC version is the only version for me and the console version felt like it had broken controls.
For example, Portal felt much harder than it actually was and there is no way I could do the same things as a sniper on the PS3 version that I could on the PC (that goes for the other classes too).

Lastly, I would recommend to people that have never played these games before to play the original Half-Life. Obviously it'll look ugly considering it's graphics were new in like 1998, but it's still a good experience that I keep going back to from time to time. In fact, I let my room mate borrow my old version of Half-Life and even without the 'HD' models, he really enjoyed his time with it and it helps him play the games in the Orange Box. It's just too bad that he's playing on his Dell laptop and it's crappy 8600 mobile video card on Windows Vista and he's having driver problems (any solutions would be very helpful).
