Not sure fully integrated and cheap/disposable go hand in hand. Depends on what type of integration you have.

I have my laptop configured in powersafe profile (battery improvement and lack of annoying fans is a plus) and I get noticeable delays when working within my IDE on certain workflows.

I also from time to time travel and I'm aware of spotty internet.

Nevertheless I'm more and more enamored with the idea of owning cheap Pinebook Pro notebooks and renting a cheap server to run my IDE over VNC.

I can't focus on work while on public transport so that setup might work just fine for me in the future. Spend that time instead reading a book, win-win
