LOL, funny you wanna decide your choice by asking only ps3 owners advice. I'd say you have already made your decision. You only want to justify your decision is right. ^^,

Well for one Wii is currently the top selling console beating both XBOX360 and PS3 in their own states. Wii has *ehem!* games that can reduce the cost of your game interest. Wii is also very family oriented and are very enjoying to be played with friends or a group of people.

With PS3, each games cost roughly around 150 at least. Most games are not to be played with a group of friends. Its common to see only 1 person playing a game while the rest is watching. Lol!

Don't get me wrong, I'd take PS3 over Wii anytime if I could. But since you're making a comparison, I'm just giving you an idea of what Wii is worth to an average gamer.
