Have an iPad 2 or third-generation iPad? Do you love retro Macs? If so, then you need to order the cool Padintosh Case for iPad (US$24.99).
While it's the front of an original 1984 Mac pictured on the case, the Padintosh actually protects the back of your iPad. You can use a standard Apple Smart Cover to protect the screen on your iPad.
The Padintosh is just too cool, and the use of MacPaint to make the screen of the "Mac" even more authentic is perfect. I couldn't help myself -- I just ordered one.
