In his column on Wired today, Leander Kahney has written about the growing number of Windows XP users who are hacking their operating system to look virtually identical to Mac OS X. “Look at the first desktop screenshot at left [available from Wired]. It looks like a Mac OS X machine, right? Wrong. It’s a Windows XP box made up to look like a Mac,” writes Kahney. The similarities are quite amazing and Wired has provided several screenshots to prove it.
