I have been using a desktop system with three LCDs and a mechanical keyboard with trackball for over five years. My mobile system is a Samsung ChromeBook. The best thing about the desktop is that I can easily upgrade, replace parts as the need arises. I have a small UPS so that power glitches don't cause crashes. The best part is the entire desktop configuration cost less than a highly spec'd MBP. When I'm on the road, the ChromeBook runs all day long, so I don't need to take a power brick with me. It's like having a MBA at 1/3 the cost.
