This may be a regional thing (or a bias thing), but I've found that most of the really talented developers around here tend to develop on Macs and keep a Windows VM handy for testing there when necessary. At a previous job, it was assumed that the developers wanted Macs, but they had the choice if they wanted. I don't think I once heard someone say "I'd really prefer to work on a PC". This was primarily a web development firm, so it didn't really matter which environment you used. There was a smaller group that was developing some .Net desktop software, and even they preferred to use Mac+Windows VM than to have a PC.
