Enough to know that the cost of buying a mac and then installing Windows through bootcamp isn't worth the time, money, nor effort when there are better Windows PCs out there.
That doesn't seem like a real quantitative answer. That seems like a deflection with an emotional response that no matter what, Apple computers are just far too expensive. Show me a Windows laptop, with 7+ hour battery life, a screen resolution in the range of 2560x1600, that practically instantly sleeps and instantly wakes up from sleep, with a PCI-Express controller giving nearly 750MB/sec on an SSD, that weighs 3.5lbs or less made of aluminum that is substantially better/faster for far less cost.
I just find it funny that for those who have done bootcamp on their MacBooks, say it's the best running Windows computer they have ever owned, and those who probably have actually never done it simply know that it's not worth the time, money or effort.
I can tell you haven't read up on the Surface Pro 3 as that problem is solved with a pen loop you can attach to a type cover or the Surface itself.
Of course I've read up on the device, I watched the entire press conference on release, I've made numerous posts on this forum about potential of this device. I've even been looking at the potential to buy one of these devices for the company that I work for.
The pen loop comes with the type cover...which of course isn't something that everybody will buy. It's a self stick adhesive so you can put it on whatever you want, including the Surface. When the adhesive gives way and you lose it, it's only $5 to replace the pen loop. Of course, if you lost your pen with it, well that's another $50.
I've just been disappointed with every release of the Surface Pro (including the Generation 1 that I happen to have), not having an integrated pen holder. Especially the new Surface Pro 3 where writing on the device has gotten substantially better, but you have to be very careful to ensure that your pen doesn't come unattached and lost.
Even still, you can buy an extra for whatever generation of Surface.
