"...and unproven tablet market." that's so true.

Maybe they thought italicizing it made it seem more realistic.

Are you trying to suggest that the market for Windows tablets is well proven?

I'm suggesting the market for tablets is well proven, as demonstrated by the 100 million plus Apple and Android tablets out there. I have no doubt that were it well done, a Windows tablet could be a success. I'm not, of course, saying I have any confidence that will ever happen.
