It's getting rediculous, the ammount of Visual Style releases for XP are either the latest Apple Tiger/Puma/Lion/Meercat/Wildebeast/Superman or some Windows Vista hackup (NOW WITH SUPER VISTA-STARTBAR WOW!).
It's getting so silly that people are releasing exactly the same fucking visual style.
Just take a look around various skinning sites and you'll see that almost every second one is either an apple os or vista. The only thing now is for people to release mashups of vista and osx. That would probably get the highest ammount of downloads too because all xp users are stupid in the face.
Seriously though, I can't believe they are so popular. It's as bad as someone ripping a website. Someone's been hard at work (in this case, apple and microsoft) to make a clean, nice gui, and some retard with no inspiration comes along, takes a screenshot, rips or reproduces each little image and pieces it back together and slaps their name on it. Get some fucking originality people. I'm really suprised that this type of stuff isn't frowned upon in the design community.
It doesn't stop with Apple or Vista either, there are a fair share of various linux distro guis floating around, but let's face it - they're way too slick to be popular.

It's been way too long since I've seen a really nice visual style that wasn't ripped or "inspired" from someone else's work.
