Yeah, it kind of makes it an awesome way to check in on your servers while you're on the go, with the free 3G on Kindles. Of course you'll get similar (100mb free 3g) with Chrome netbooks when they come out.
Only in the US, though...
isn't their free 3g worldwide? Though stripped down or something?
I applied for kdk access when it was first announced in January. Never a word. I think Amazon moved too slow here, because now I don't really care. I've moved on and enjoy building for the iPad.
Ya, they really need to take it out of beta and just let people use it.
