Frankly, I'm sold too. This is going to sound kinda lame, but I am generally in Chad's position. I wait for the prices to come down a bit, as I don't have much time for videogames and so there are loads of games for the previous generation systems that I never got around to that I can play until the new systems are more reasonable.
...BUT, this is different. I REALLY want this thing to succeed. I was leaning toward PS3 in a couple years, but now I think I'm going to try to jump on this boat just to do my part, so to speak to help bring 3rd parties to the platform to begin with. Which will bring more consumers. Which will bring more 3rd parties. And so on.
It's just one of those things, like Psychonauts. I steal almost all of my Xbox games. I download most, and if I want something specific, right now, I just rent it and rip it. But I want Tim Schaffer to succeed so much that I ordered Psychonauts a few weeks ago, in spite of being so overwhelmed with school and work right now that I haven't even opened it yet. But I know that sales are low (even though it's apparently a masterpiece). I wanted to pick it up while it was still full-price and I'm sure that a price drop is in its very near future.
So, anyway, I am so impressed with Nintendo taking this bold step, and I think that it has so much potential, that I'm going to try to jump on this thing at launch. For any console to be a success, somebody has to do it. Generally I don't want that somebody to be me, but I'll try to make an exception here.
