I hope some big names, like SuperMicro, take this seriously and get something in our hands soon. This would be perfect for two socket 1U servers or some tiny blade units (those SM deals with four blades in a 2U kind of thing.)
There are some fun projects that you could do with this. Although for wearable I guess it is a lot harder to really do something cool yourself. Wearable Arduino already handles things like wearable lights. This would be more for having a secret screen inside your coat to watch movies on.
Depends where you are, some places it's still very actively used. We just made a deal for a new web development project called one of the big caveats was that we had to make it work well on Blackberry because all the sea levels only use blackberries. It also happens to be a Canadian client.
