This poll is too black and white. For example I don't think I will ever be deploying Windows 8 on Desktops or Laptops, However it MIGHT be deployed if we ever get Surface tablets in. I definitely see the benefit in having a Microsoft tablet integrated into my AD instead of trying to shoehorn in an iDevice or android (although androids work better). But being able to install my Windows only VPN client on a Microsoft tablet and having full office from it, would be pretty slick. However the Metro UI will never fly on traditional computers. Period.

So if the question is will we ever deploy Windows 8 on traditional computers and laptops in our org, hell no. Will we consider deploying it on tablets, yes.
