There's no reason why OEMs should be scared or even feel threatened by this. Although I'm not a huge M$ supporter, they do this kind of stuff all the time. They layout a standard, show the OEMs, and then the vendors duplicate it and personalize it. There is still plenty of money to be made for OEMs that choose the Windows 8 platform for their devices. All companies like Acer and ASUS need to do is just release a tablet that actually comes with a digital ink stylus, or perhaps built-in mobile broadband support. Simply take the components that Microsoft hasn't included, and put it in yours instead. Tablets are innovating all the time so there's no reason to think of this as a threat. Consumers will continue to choose what they feel is right for them. If anything, a bold move like this will make vendors more confident in Microsoft's abilities and they'll stand by their side.
