I know I would buy this sort of device in a heartbeat. Being in a Northern Climate, I want to spend as much time in the summer outside as possible, and with working from home (and free from having to stay stationary, inside all day), it would be nice if my computer could be as portable/flexible as possible.
This seems like it wouldn’t be that hard to put together. If it can be done DIY, you would think that a small-batch operation could be created. When I heard about the Lenovo mod a couple of years ago, that seemed like a no brainer.
There have to be lots of people who want to work outside, right?
