I've been using it since the day the beta came out. I've been an Apple fan for a long time but I think this might be the best thing they've ever done.

It makes programming approachable to nearly anyone on a device that's approachable to anyone that can afford it.

I heard someone on one of the TWiT podcasts talking last week about teaching their 6 and 8 year old to program using it and that they were talking about creating real-life functions to do household tasks IIRC.
