The Wii is alright online, lag just depends on you and your opponents connection, you shouldn't have a problem because I too am running cable internet and have no issues for the most part. An xbox 360 will give you more online gaming out the box, but the Wii has quite a few titles coming and they should be good online. Only cheating I've heard of is people disconnecting when they're losing on Strikers. Log in time isn't too bad, though I am a bit impatient when it comes to games loading. Either way you make a good choice, you most likely will get a lot of people telling you to get a Wii though.
