People who hack their system files know they can do that for free. So I think a lot of the WindowBlinds bashing is emotionally driven -- they want to justify their unwillingness to pay for WindowBlinds by convincing themselves that msstyles are somehow better.
I'll see yet another Luna recoloration (something WindowBlinds can do on the fly) get posted on some site and see it praised to high heaven. But when someone does something really original and cool with WindowBlinds they start trashing it.
Maybe if these guys came out of their mom's basements and got lives they might be able to broaden their horizons.
They're worse than robots. They're more like drones. Because let's face it, the default Windows XP look is pretty "bloated". The skins they tend to praise aren't exactly optimally designed for performance or productivity or screen space. They're just whatever Microsoft tosses out modified slightly. I swear if Microsoft made the title bar 40 pixels high, I bet half these guys would still drool over it.
