Yeah, I've given up on Gnome. Currently using Enlightenment on my desktop
but that would not be good on a tablet. Sounds like Squeak has not become
blotted as hardware specs expanded. That's good.

Why would the port "just work?" Does the Freescale chip execute i86
instruction set? (I feel like I am in over my head here.) My thinking is
that the ARM chip will require its own vm, then an image will "just work."
