Any good reasons to buy the Nintendo 3DS?

I thought about, but to be honest I'm not impressed by the launch games lineup when it first came out. Many people are excited about port released of Zelda from the n64, but even that has no value to me when I've already played that game on the N64!! It just seems like there going to do remakes of previous games and port them over to the 3DS. I'm tired of seeing mario 1, mario 2, mario 3. It's time to retire mario. Yeah, those are nes games, but I'm just giving an example of games that repeat themselves over and over after many, many years.
