Should I ask for a Wii for graduation?

[misseureka]

I'm not a gamer--everything I know about video games comes from Zero Punctuation and Penny Arcade--so forgive me if I seem ignorant here.

I'm about to graduate from high school and my mom wants to get me a graduation present. Her idea? $600 earrings. I'm thinking of asking for a Wii instead, something to play with over the summer and take with me to college. I hear Wiis are good for casual gamers, and it would be something nice to do with friends. Do you guys think I should ask for a Wii? And if so, what games should I get for it?
