Well, I agree, I'm using a new imac with dual-bootcamp Win 7, and it seems to be the best combo so far, apart from some apps I use which only go as far as XP. I understand Snow Leopard has some similar ishoos, and I'm half with Keef about exclusivity..
To make it clear, I have used Macs and PCs in industry and education for many years, and can appreciate both sides of the discussion.
Keef - Mac folk are indeed evangelical..
