I think the author spun his article with the concept that a Mac is 'better'. In my opinion the real point of the article should have been that Apple is branding their products as 'premium'. Just like anything in life just because someone has branded themselves as 'premium' certainly does not preclude the possibility there is something better out there. In fact I think Lenovo markets their laptops in a similar way by catering to the business user. It isn't to say Dell/HP don't make a products that can easily compete with a ThinkPad, it's just that when you think of a 'business' laptop Lenovo wants you to think of a ThinkPad.

Having said that I own a ThinkPad W500 and a Macbook and think both have strong/weak points, but given a choice of only having one I would probably stick with the Macbook, simply because I can do anything I need to with it (a la bootcamp).
