That isn't the same thing as rendering them properly, and the fact of the matter is, no matter which Office competitor you use, it will scramble Word documents that do any serious formatting at all. As for PowerPoint, you have no idea just how bizarre the results can be until you try running a PowerPoint animation in a competitor's piece of software.
There is a work-around that lets you provide Microsoft Office to employees using other platforms: You can run Windows on a server in the data center and use VDI to push it out to client devices. Think that makes Windows less important as a client platform? Of course it doesn't -- Windows is still the client platform, but you'll run it in a virtual machine instead of natively.
Microsoft gets a lot of dings because it just can't seem to get things right in the mobile space. It's an eminently fair criticism -- every version of Windows Mobile so far has been at least one step behind the industry, and there's no hint yet that Microsoft has the ability to leapfrog its competition. It's natural to figure Microsoft's presence in mobile computing is and will be limited to laptops, which will remain the portable devices of choice for those who plan to do serious work that requires a keyboard for quite a while.
For those who think they'll be happy with a tablet/keyboard combo, perhaps they will. If they're working with business documents, they'll do so by running a Citrix or VMWare client on their iPad or Xoom.
Here's your take-away: The increased importance of other platforms represents an expansion of what you'll be responsible for, not a substitution. Windows and Microsoft will be important for a number of years yet -- but so will other platforms and players.
