Okay, I’ll admit that I too tried to get one of the HP Touchpads when they went on fire sale. It seems like a nice tablet to tinker with for $99.00. I was not able to get one for that price. Anyway, I stumbled upon the below website link the other day and came across the HP TouchPad Wallpaper.
As you can see from my screenshot, it works and looks great on the iPad (I’m using it on my android tablet as well because I love that blue)
(There are other HP Wallpapers there as well on the link)
