I have the component cables. If you have a widescreen, I strongly recommend using component cables. You can actually "hack" your existing cable to use component but it's not pretty, though it works.
I noticed a big difference when playing Zelda. I've played Madden, pretty cool. I have Trauma Center but haven't even opened it yet. Busy w/ my DS Lite playing Phoenix Wright. Yeah, I'm a gamer...
The Mii's are pretty cool. I share mine w/ a bunch of other gamers and when you play Wii sports, their Mii's show up as other players.
