What runs through my head when thinking about laptops like this is while they are good why pay $2k for it when you can get a Macbook Air for soooo much less?
Dont get me wrong I am no Apple fanboy, heck I dont even own a Apple laptop.
But the Macbook Air 13 or 15 will perform similar, if not better, be silent, blow away Intel based laptops in battery life, and have better build quality and support than what HP offers.
I've always been a Windows laptop kind of guy but with more and more workloads moving to the cloud the Operating system is becoming less and less important.
