It seems like more ed-tech leaders in the US have ordered one than I thought would. I guess I'm pretty used to the idea that folks aren't really interested in controlling the cost of hardware, having a durable machine actually designed for kids, free software, Python, ZeroConf networking, Jabber, Squeak and the dozens of other things that I like and are baked into the XO. So from my point of view, this is an ed-tech coming out for a whole stack of things I've advocated for years.
The problem here is that what people are going to see and form the basis of a big part of their opinion is the Sugar shell. I have no idea if it is going to feel fully baked. So... fingers crossed!
