Guide: How Not to Conduct Yourself in a Discussion

I was having a discussion with an acquaintance of mine who seems to like the Microsoft Surface RT more than most people. This is the best (and last, for a while) bit from our conversation:

Basically the Surface is a tablet designed for intelligent, capable people who will buy them, and the iPad is designed for the masses.  A basic dumbass friendly tablet for people who struggle to cook pasta.  That's okay and their business model is great and profitable.  But since i don't care about that, and since MS are still making pleanty enough money to satisfy me, i don't see their ecosystem dropping off the board any time soon and therefore, their Tablets only selling in modest numbers is fine to me.  It's cool, then it doesn't become a pleb item.

Damn, if only I could master that pasta. Maybe one day.
