Most tablet makers would kill to have this much developer interest. I'm fascinated by Silk and have wasted the better part of the day trying to figure out exactly what they're doing.

I am hoping that Amazon gets a developers guide up soon that fills in more of the gaps. Already on EC2 and I want to start experimenting.
