I think I love everything about that sentence.
An easy-to-clean keyboard could definitely find its uses in dirty environments. Even if the screen is glass, the keys should protect it pretty well. Depending on how scratch-resistant they are. For CNC, being able to customize the keyboard seems really useful.
It's interesting that they say you can play video on it due to the built-in 8 GB storage, but it's not available as a display to the host. Their point that the "mouse cursor could get lost on the keyboard" is a nice rationale, but it does feel like an odd limitation for such a powerful device.
I wonder how complicated it would be to allow customization based on SPAs. Their list of initially supported applications suggests they are not tackling web apps at launch. E.g. the Google Docs/mail suite would be interesting to me.
