A few people are baffled by this, since it appears that Google and other applications seem to have a real solid product with full collaboration and editing functionality. WebmasterWorld members suspect that it won't be long until Microsoft gives more access to the platform.
I suspect editing capability will come if Microsoft starts feeling a real pinch from fully functional online suites.
This provides document accessiblity from anywhere, which is at least a step in the right direction. This lets them postpone the inevitable decision of how to charge, or whether to charge at all, for online document creation and editing.
On the other hand, if Microsoft chooses to charge for the program, users believe that Google Docs will win out, since it remains free.
And of course, Linux users are a bit suspicious in general, but they believe that the tools will still appeal to the average computer user.
