For the past several years one of the strangest and most interesting platforms with an app store all its own was the Livescribe series of smart-pens. Now, it's just another ditch to be dug in the development graveyard. After three years it will be closing up its SDK shop on July 22nd, and no more submissions too its app market will be accepted. The store will remain open for the time being, but the company won't guarantee compatibility with future models or firmware updates. Instead it will shift focus to cloud services like Livescribe Connect. But, don't get too worried, we're sure the healthy hacker community will keep you knee deep in text adventure ports.
