re: Why Microsoft Won't Release Office For The iPad
It's almost as if Microsoft is trying to figure out which throat to cut - their own or their users.
As someone who has to deal with Microsoft's support for their Office 365 product on a nearly daily basis, since I'm supporting an enterprise that utilizes that service, either things work or they're excruciating.
To be honest, I generally deal with the Hosted Exchange, Lync and Sharepoint products - but I'm aware of organizations who have those services from Microsoft but are looking at moving them back in-house due to a lack of service stability. Organizations run on e-mail, IM and knowledge sharing these days.
With that kind of experience, I would be extremely hesitant to endorse the Office Web Apps for any enterprise setting. Microsoft would really need to make some strides in the stability of their ability to provide service.
As far as getting Office on your iPad or even Android, for an organization of sufficient size, I'd recommend something like a VDI implementation where people could use an iPad based client to reach a real Windows desktop and use real Windows applications on it.
For Microsoft to consider putting Office natively on the iPad would be them surrendering the tablet market and effectively turning the Surface line into the next HP Touchsmart debacle. Ubiquity comes at a high price - you can't try to lock people into one application suite on a small number of platforms, especially in this day and age.
