I saw an iMac setup at my local Best Buy store in El Paso, TX last week. I was very surprised because I heard no announcement of this happening. I guess they got an early start. Funny thing is, the had it booted to Windows XP with a crappy looking background (looked like some kid scibbled with the mouse in Paint). I went to Startup Disk, told it to boot OS X automatically, and restarted. I then, opened Photo Booth, took a silly picture, and left it on the screen.
