closed source is probably the wrong term. I bet you can get them to honor their GPL obligations and give you the linux source that they've used.

But the add-ons (the GUI, the apps) those probably are NOT open source. And they're locked down. I'm told that they don't provide an open SDK, nor a means of loading in new Apps for their GUI app launcher to recognize.

Which is what ruled out the Mylo1 for me. I hear the Mylo2 isn't any better, in that regard.

Though, franklin has a Mylo1 model that they sell (re-tooled to act as a dictionary and learning tool for kids). It uses SD cards instead of Memory Sticks. That's an upgrade if I've ever heard one :-) But different software, and still locked down, as far as I've heard.
