Microsoft injects more juice into Office Web Apps

They already have network drives

it seems Microsoft are, in effect, just making their SkyDrive into another network drive.

Microsoft have spent 30 years making operating-systems for personal computers, but now they are failing to adapt to impersonal computers.

If your documents were stored as a XML tree, different people could work on different branches of the tree. Perhaps, different branches could be stored on different computers with a cache snapshot of the last version stored locally. Unfortunately, Microsoft Office is a collection of widely different applications bundled together: internally they have different libraries and data-structures to do the same thing from a user's point-of-view. You can embed one type of document in another, but both applications have to run to support the different ways the same data is stored. (KOffice have tried to share colour setting, font setting, shape drawing, etc. amongst the different document types. The different office applications could degenerate to template managers and template filters. It seems nonsense to have two separate documents: slide-show and brochure: about the same subject, when they are just different representations of the same data.)
