Sure there are also lots of reasons not to buy Burton (slightly higher price, annoying marketing, not wanting to use what half the people on the mountain have, not 'core'/poser enough, etc.), so should weigh the positives against the negatives and make an informed decision based on one's own needs and preferences.
But there are certainly are plenty of good reasons to buy Burton...
Don't get me wrong, I don't hate Burton. I actually ride with Missions and Ruler boots and love them. Normally when I'm looking for boards, Burton is one of the last places I look because they are so expensive. I just feel like you can pay less for a board just as good.
