Please note that I do not condone piracy of any kind!
I was actually wondering if anyone has been able to get their hands on the developer preview for OS X 10.7 "Lion" and successfully install it. With the Mac OS evolving more behind-the-scenes, it would be interesting to know exactly what the changes are from Snow Leopard (10.6.x) to Lion. Unfortunately, the best and easiest way to get this OS seems to be through pirating, so I'd much rather see something legit than that. Just one of those "it would be cool if" topics!
