I agree with your post up to the point at which you begin trolling about formats. Yes, tech staff do have to wear two hats to support both Windows and Mac environments, but a few creative types using macs in a windows business rarely amounts to major headaches for IT staff. Yes, there are some format issues early on, but users adjust quickly and FAQ pages (and tech staff templates) get updated quickly. Has the mac penetrated business? I doubt it, although I have no data. Is it hard to run a mixed environment? More so than a single-platform environment, but not terribly so in limited situations. Does letting employees choose the platform that causes the fewest headaches for them (vis a vis familiarity, software availability, format compatibility, support, etc.) improve productivity and work satisfaction? I would strongly suggest so. But perhaps I'm wrong.

Interestingly, when I went to the doctor for a persistent fever, coughing, and sore throat, he advised me that I was likely to have an influenza variant but that this health division was no longer doing swabs for H1N1 unless you were admitted to a hospital. This means that, at least in my area, there are probably a great number of cases un-reported, despite having presented themselves to medical personnel with typical symptoms. Oh, and I live in Saskatoon, Saskatchewan, Canada, home of ~200 cases.
