I think consoles are inherently better simply because of the controls.

With a console, because the controllers are the same, the game designers don't have to worry about how your specific wheel,joystick,controller,mouse/keyboard is designed and configured. You'll always have consistent gameplay across every system. Also, you don't generally have to install games for consoles (there are a few exceptions), as you do with PCs.

No installation also means no updates. Developers must deliver a non-buggy product or risk losing sales. PC games often ship very buggy and people deal with it since they can just download updates...

The only real advantage I can see for PC gamers is that the graphics are better for new games if you're willing to shell out a couple thousand for a serious gaming machine every year or two. Many people don't seem to understand that graphics != gameplay though. Consoles simply have better games and a wider selection of titles to choose from (Solitaire or Bejeweled don't really count on the PC side).

Handhelds are just a couple generations back from consoles and share most of the characteristics that they do, except Nintendo should stop remaking all of their handhelds. Do you really need 5 different Gameboy Advances?
