there's only so much you can do...
six years or so ago, the company I worked for bought a nice big 24" iMac for the Marketing team because "you can't do serious graphics work on a PC"
They installed the Adobe Creative Suite, got the IS department to get the machine online and connected to the company (Windows Server based) share drives.
Then the complaints started:
Why can't we access the Exchange server from the iMac? (Um, because Office for Mac had a terrible email client?)
Why can't we print directly to the office colour copier and access all the cool stapling and folding function? (Um, because, as a commercial unit, Canon had never written drivers for OS X?)
Why? Why? Why?
And the answer was always, after researching a solution, "Sorry, it just doesn't work."
So what's IS (Information Services) to do? Write their own printer driver?
Yes, connectivity has gotten better, but you can't always work around some issues, and you also can't help some people on the Mac side of the fence see past THEIR own prejudices (Seriously: otherwise intelligent people were telling me only a Mac could run the graphics packages they wanted - and they didn't even demand Quark!)
Ultimately, that machine was set up with an icon on the desktop that opened a remote desktop connection to a Windows virtual machine on the server that then connected to Exchange. Files could be output to PDF, copied to the VM, and printed to the copier from there...
the hours wasted, trying to support that machine...
