What it is like to go from pair programming to not pair programming:
- You waste time learning a new editor in a new company because your pair is not there to type exemplary keystrokes
- Less motivation, pairs keep each other going
- The category of bugs that you didn't even realize pairing was preventing -- they all reappear!
- If you suffer from mental deficiencies (e.g., ADHD, Asperger's), you lose your train of thought, that MentalStateCalledFlow.
