with companies less profitable than google?
Mac's are expensive
most people don't own Mac's personally
lots of people use personal computers to VPN to work
how would it work with the files on file servers people use to get work done? like MS Access databases?
About 30% of the folks in my company run Macs. In terms of sheer numbers not as many as Google but still multiple tens of thousands of users. We do use Microsoft's productivity suite extensively but use native versions of Office where we can, and Windows in a VM where we can't. I can't remember the last time I had to fire up my VM, though. The native VPN client works great, and I can also natively access CIFS file shares just fine.
