Are you saying no one will be able to write a defrag or registry editor for Windows 8 using Metro/WinRT? How then will we defrag disks and edit the registry?

Given that many will still be operating without a constant network connection, how would they save their work? How do they create a Word document for example, If no Metro/WinRT applications can write to the local disk?

Or, are they saying that the Office suite will not be Metro/WinRT based?
