Windows and Linux

The car analogy

• Windows is an SUV. Linux is a hybrid.

The sex analogy

• One is like having sex with a partner who doesn't move at all. The other is like having sex with a lot of power play. Frustrating at times, but rewarding.

The religion analogy

• One belongs to a denomination that fears the number 13. The other is an atheist who pretends at times to be a Pastafarian.
  

The shoe analogy

• One is a pair of boots on the verge of going out of fashion. The other is a shoe kit that comes with a manual teaching you how to be cobbler. And how to design a shoe that stays atop of fashion.
  

The significant other analogy

• One is the kind who had looked attractive at first sight, but who you now perceive to be unreliable and emotionally distant. The other caused you immense frustration, but is always ready to learn and compromise.

The teenager analogy

• One is the party boy. The other is the introverted studious one who seems to know something about everything.
  

The pedagogy analogy

• The first one believes in "no child left behind". The other one believes in self-learning.

The young parent analogy

• One is your standard authoritarian parent. The other is overly permissive, but slightly negligent.
  

The married couple analogy

• The first is a both in work, no kids couple; he works in customer service, she works in advertising. The other one has the guy working in a home office as an indie game developer, with his fellow colleagues coming over for visits as she tends to the house and blogging actively. (well, this analogy is quite digressive)

The elderly person analogy

• One constantly nags at you because he/she has to go to the loo. The other one has a lot of moral personal experiences to tell your child.
