MS can only dominate tablets by upsetting their enterprise segments. Microsoft's personal computing empire is built not directly on Windows and Office, but on the million little customizations and plugins that people build on top of them. That's where their lock-in comes from these days. If they can't put that platform on the new hot computing hardware, their advantage is gone. New people buying a hypothetical "touch first" MS tablet would not only be free to choose other applications than Office, but their enterprises would be forced to rewrite their MS-locked solutions. Thus making it easier and easier for IT groups to push alternate desktop and server platforms. If Outlook is reduced to just-another-mail client, and the workflow/management 'applications' built on top of it have to be serviced elsewhere, you might as well let employees choose mac or linux machines. And you may not even be able to justify Exchange itself after a few years of that.
