Consoles are for small gaming parties with friends who come over to see how much they can glitch a game for laughs.
PC's are relatively expensive for connecting with almost anyone on the globe to play massive game with.
They are all designed for gaming, but consoles fit certain niche's better than a PC can, and vice-versa, and there are some genuinely good games on the Wii and the other consoles, such as the Metal Slug Anthology for the Wii (Frustratingly satisfying gameplay at it's finest).
Some people (like my brother) argue that Console control schemes are better for racing games which does make sense, they are all designed to do different things correctly and I think they all do what they are meant to.
