Well I finished breaking, and I've had a day to play around. I followed the step by step post on page one and had no problems. It's definitely worth it, and the more I tinker the more I find that I like.
My only real complaint would be that there is so much available that isn't 'native.' a lot of what I want to try would require using a computer with net access. But I don't even keep my computer at home. I'm one of the rare birds that does everything on my iPhone. I hope to see that become easier or more accessible as the dev community grows.
But really that's a selfish and unjustified 'complaint.' Its definitely worth it. And it was VERY easy!
