I don't know the percentage, but some do prefer it, and I'm among them. I'm surprised so many people express any preference, though. My take is that the Fn key is an abomination and it's not present on desktop keyboards so either choice of location is wrong. If I could, I'd remove both Fn and the 'Windows' key. Neither my Chromebook nor the T40-series Thinkpads I first used have these keys, and they are noticeably more comfortable due to the larger Control and Alt keys it permits. I'm also surprised people complain about this but not about the layout of Apple laptop keyboards, where 'fn' is also in the corner.
