Perhaps not large enough on its own, but I don’t think a Windows on Arm (WOA) sustainable market can afford to miss any of the PC faithful. As a matter of fact, ‘enticements to investigate’ may be just the thing to get the stubborn enterprise customers on board.
What I’d like to see from Windows 8.2:
‘My Sandbox Macros.’ This may actually be for Office Gemini, and only applicable to WOA 8.2.
The notion is that an owner is implicitly trusted on their own computer. Anything authored by that owner abides by Microsoft’s blueprint for a sandboxed devise. So, the Office VBA IDE (available via separate download) would require the user to re-enter the owner passphrase before proceeding. Source code can then be entered, via typing or a text based copy and paste, and debugged. Once completed, the code is compiled to a devise specific binary. In other words, can only be used on that one machine. Inter-machine connectivity/automation can only occur between devises registered to the same owner.
Perhaps WOA 9.0 can allow third party apps to expose a public COM based API, creating a MS Office integrated, highly mobile, line of business computing.
Remember, ‘the most productive tablet ever built.’
