If I were on the Surface team, I'd be A) elated that the product is generating discussion, and B) watching this thread (and others like it) like a hawk and taking notes. From the right perspective, this thread looks like a room full of people all competing to be first in line to tell Microsoft that they'll buy their new product if they just fixed their one complaint.
Negativity is wrapping paper on the gift of feedback - it is to be torn off and thrown away, because it has no value.
I once worked at Microsoft on a product that was actually getting almost entirely positive feedback (while still in preview) for once and ... it was kind of frustrating. I started scouring the internet for "<product name> hate" (and did find haters, some with interesting povs) :)
