That cost analysis is useful only if you will be restricting the use of the PC to things a console can also do (whether if can do them better or not). If you include the things that a powerful PC can do or help you do better that a console can’t, it makes the balance much more even since you can get much more out of a PC. As for games alone, if they would allow a mouse and keyboard to be used for control in games on consoles that already support it hardware wise (firmware/USB ports present), that would take away one of the bigger reasons I have for shunning consoles. The wii is the exception in my mind because I don’t and would never play the same games on the wii as on a PC, and the wii is more of a party console.
