Me? I run a new Macbook Pro 17 (+ VMWare + Boot Camp + Win 7). But the sub-notebook class is attractive for way more than email. That's the whole point of having a machine that can run Windows. This would be like trying to sell as scooter that was banned from the freeways. Most people are going to pass it over for more practical models.
Scooters are banned from the freeways and they still sell. Not to people that want to drive them on the freeway, but to people that want to use them for their designed purpose.
