No, I'm talking about their day-to-day business before we even came along...MS Office docs are the norm in b2b transactions, and as a supplier the burden is kind of on you to take the crap your customer gives you. Some of the employees were just happy to have the more familiar Office experience...one comment was, "Oh, good, it's like the one I have at home now."
I won't even start on the cobbled mess his servers were in...however it starts with using WINE to host their ERP and goes downhill from there...
On the bight side, he did get a bunch of people to stop using IE.
And actually FWIW, I set up an Exchange 2k7 server at home (TechNet ftw) a few years back, having never set up an e-mail server, period, and I had it working fine in 2 hours, and it's still running to this day, because I am too much of a procrastinator to update it to 2010...
