What prompted you to dig out a weeks-old forum post to base a personal accusation on a peculiar choice of spelling? Apart from the fact vogonpoet might have chosen the spelling in a tongue-in-cheek way - as he was talking to Angelus, who I'd refer to as an open source fanatic if I were sure what he actually is - there is also a gap between not liking Windows, or certain aspects of Windows, and actually preferring another OS.

(I could mention that there are little things more inconsequential than an individual person's attitude towards computer's operating system, but seeing as I already took the time to type up this post myself I can't convince myself that's a valid point either.)
