I have thought of this and what advantages I would get. Other than a fun project, I saw no advantage. We work fultime. To help you see my point, my Angel and I are both moderate geeks and in the IT industry. We have a media and document server at home with a raid. We each have an 18" laptops, 12" tablets (w/MS OS - not android) and smart phones.
Most people have what they need in the laptop they use every day. We do. We take a laptop and tablet with us and share info off of those. This keeps us working off our current info and always updates systems. We could not justify another computer for the MH, though for us it would not take much convincing. The reason we do not do it is that it simply does not provide us anything.
Now, if I were refurbishing or designing our MH from scratch, there would be great opportunity to incorporate all electric and electronic systems into the coach, as in the multi million dollar coaches.
