I'm not sure why you think "anecdotal experiences" are invalid when people are talking about a personal choice. I.e. I don't need some sort of double blinded study to "prove" Mac laptops are better. I've used other laptops, and I have a strong preference for Macs for a myriad of reasons that have nothing to do with marketing (to be honest I can't even remember the last time I saw an actual ad for a Mac). You may disagree, that's fine, but it's silly to pretend the personal preferences of others are somehow invalid or less than.
