I understand the desire to categorize OSes into neat little boxes "phone", "tablet", and "desktop" but that's not the reality in the Windows world. Windows has 1 OS that is definitely "phone", and then it has another which is a hybrid of what we currently see as a "tablet" OS and what we current see as a "desktop" OS. Windows RT even falls between these; Windows 8 (including when on a tablet) falls between as well. With Windows being such as success in desktop PCs, a blurring of the two ideas is strategically important to Microsoft. If people starting thinking of tablets as PCs it benefits Microsoft. They are even moving towards having laptops be tablet-like with touch interfaces; and transformer tablet/laptops further blurs the line. From an app perspective this could mean either 1) that the reach of Windows will pressure app developers into supporting the platform or 2) that due to its closeness to traditional PCs, and most users being on traditional PCs, app developers will see their website (if they have one) as good enough. If I'm predicting, I think the former will happen.
