Pros: Visuals, Information... Nature at its best.
Cons: zilch - nada - zero
My aunt and uncle bought this for my boyfriend last Christmas and it's just... beyond words. I'm a Discovery Channel nerd and travel/documentary (still) photographer and this compilation of animals, landscapes and pristine nature is like putting fireworks in my veins. Although, that sounds a little painful - not what I was going for...
I can't say enough good things about this body of work. Get your hands on it somehow. Pool a group of friends together and split the cost - whatever you have to do, it's worth it.
Nature speaks for itself.
