The Wii is f-ing awesome. This baby can barely stand on his own yet he can already easily serve, volley, and even skip his own replays!

The Wii works on all levels. You can go out Wii bowling on a daily basis but still occasionally lose to someone whose never even held a Wii remote.

It can also be a good excuse to take out your agression on an underperforming flat screen TV.
