It isn't a requirement to love Mac, or ANY brand / product.
Why people get soooo bent out of shape when the gear they own isn't praised by someone else. Who the hell cares?
Certainly, stating obvious incorrect facts or just being a plain troll/shill is different, but people buy and stick with what they have because they like it. That is all that matters.
It would be pretty damn boring if we all had the same gear, same tastes etc..
