Love your "geekification" work on your kid!
I'd resisted it for a number of years, but after he decided to save his allowance for most of 2009 to buy himself a laptop, I figured he was headed that way.
He hasn't gotten into the coding yet, and I'm not going to push him. I'm here when he asks how stuff works, and usually that is a much better experience than me forcing him to pay attention when I want to tell him about what I think is important 
Thanks for the comments guys!
BTW, did you all see the other projects in the Tom's Guide article? - some of that stuff is pretty amazing!
