I work for a large IT company which I won't name here. In the past they let managers (but not the average employee) choose between Macs and PCs, and guess what, most of them got Macs. Then another big IT company bought us, and that company happens to make PCs. Of course they stopped giving anyone the option for Macs, but some managers are still using their Macs, as I have recently seen in meetings. Additionally, from a quick conversation I had with the rest of my team (about a dozen people), about half use Macs at home.
