Most OS usability articles are about how nice Mac OSX is compared to Windows. It's something that mac zealots like to rave about. Contrary to popular belief, I'm not a mac zealot: in fact I find the zeal or scorn from either camp somewhat ironic. If you like macs, you're clearly a zealot, and if you like Windows, you're clearly a dummy.
If I have any apparent bias, it's an appreciation of the innovations that macs offer in a Windows world. If Microsoft emulate Apple's good ideas, then good for us. Likewise, if Apple emulated Microsoft, then good for us.
This article is a rarity in that it addresses the latter.
