Well, I won't do that again... I found a cool site that talks about skinning your WindowsXP machine (or any modern Windows) to look like the Mac OS X environment. Having never been a MAC fan I decided to check it out. It's a bit cheaper than buying a new MAC. :)
One thing to remember is this. If you are testing a beta service pack (ie: SP2) make sure to remove it before installing something that replaces system files.
Having said that I am now reinstalling all my applications on a nice fresh install of Windows XP SP1 and I did get the OS X skin installed. It's quite nice I must say, I just have to get used to having the task bar across the top.
