I'm on kubuntu, I could run it in a VM though it's much simpler to open google docs in a new chrome tab and more than enough for my needs, so why bother? It's not the right tool for the job if google docs gets the job done for me with much less hassle.
I'm not an MBA number-cruncher type, but all the product managers at my (otherwise Mac-heavy) company insist on running Excel through a VM or a Boot Camp installation because the Mac version of Excel doesn't offer a lot of the functionality that they rely on in the Windows version.
There's more than enough hassles involved with running a company - doing compatibility work for office software shouldn't be one of them - just use what is the industry standard.
Also, if I have to worry about this kind of thing, it means I'm working with people who voluntarily use NT. Nothing good can come from that. ;)
