I bought a Surface for three reasons mainly. First, it supports Flash, and when I tested tablets out in the showroom, I was able to watch online lectures on the Surface and not on the iPad. Second, it gives access to the file system, so I can organize my large collection of scientific pdfs on disk the way I want to. Third, it has a USB port. I was rather astounded that the iPad did not, and perhaps Apple has changed this, but that alone was a showstopper for me. What it all adds up to is that Apple created their usual walled garden for the iPad, and in this instance the walls eliminated much of the value of the product, even for such elementary uses as reading scientific pdf's, and watching scientific lectures online. I will say that the Surface also had some restrictions on Flash originally, which I quickly discovered when I got it home, leading to a rather testy email from myself to Steve Ballmer. This was very quickly answered by the head of the appropriate department, and they have changed their Flash site approval model in IE to be much more open.
