So the reality is that there’s no such thing a no-compromise dev setup: Either you optimize for a desktop setup, or for portability, or somewhere in between. If you have the ability to have both a desktop and portable setup, such a pair I almost always going to be superior to just one medium sized laptop: Your desktop experience will be better with massive high resolution monitors, and your mobile experience will be better with a lighter, slimmer device and longer battery life etc.
