Steve jobs during the iPad keynote mentioned how people customize their computers with their own wallpaper... Though all of our Macs come with preloaded wallpapers i'm wondering what is most likely the case in your situation? Is it... 1. Some cool wallpaper you found online? 2. Personal photo you took such as friends/family/event? 3. Pre-loaded Apple wallpaper such as the aurora SL wallpaper? etc... I'm also very curious as to how often you change your wallpaper...I used to do it all the time, doing it daily, then weekly. Now I just keep it on end for weeks until i'm bored with it... ...mine is usually a folder of cool wallpapers i found online, though i've always wanted to display some awesome photos i've taken. You?
