That applies only to the exclusives and that too they shine in terms of game play alone, not graphics and they would make a much better experience if the same game is optimized for PC. Killzone 2 considered to be one of the best looking games on PS3 wrt graphics seriously disappointed me in that division. KZ2 looks like a 2~3 year old PC game. A High PC + Console is a good combination, I have my PC and 3 consoles (360, PS3 and PSP) and don't miss out anything on the gaming front.

But a console alone is not much of a gaming platform for a serious gamer who wants to play a variety of games and in quantity. A console is suited only for the casual player who do not ply more than 10~12 titles in an year or those who have only one or two game like Halo 3 or COD sends their entire time for multiplayer. Further more, a PC works out a lot cheaper than consoles in the long run for people who tend to play a lot of games. If you are content with the quality you get on consoles, then the PC will work out even cheaper.

If you want to stick to both PC and consoles then that fine, but if you want to replace your PC with a console for gaming purposes, you should do that only if

1. You are a casual gamer who rarely finds time for playing 5~10 games in an year.

2. You are into multiplayer and keep playing those same one or two games every day.

3. You do not care much for graphics as part of the gameplay experience.

4. You are not too tech savy and would like to have a no nonsesne gaming (no technical problems to worry about) even if its not in the best quality.
