It is an odd social phenomena. People who become militantly for or against brand names or technology formats. As if a brand name or particular format were an equivalent to a political party.
Only recently the History Channel had on a bizarre, yet amusing show about the "Cola Wars". Where apart from two of the largest beverage corporations duking it out for the number one spot, a large share of their respective customers seemed to echo the same bias. That essentially they "married" Coke or Pepsi.
Then again there were also the VCR wars. Sony Betamax versus JVC VHS. VHS won. That was yet another war that I didn't take sides in. I enjoyed owning both formats. And of course a few posters over the years have made some colorful comments over a preference of XBox or Playstation. Whatever.
I prefer desktop systems mostly because I build my own. Though if someone gave me a decent laptop, I'm sure I would enjoy the portability.
