I think Apple will be coming out with the "iBall".
"The iBall is a wireless, spherical device, designed in California to add a new dimension to everyday social networking. iBall incorporates a proprietary design feature which significantly cuts down on weight. All components of the iBall have been streamlined so that they are incorporated only in the thin external shell, leaving the center of the device magically filled with only air. This also helps to minimize the environmental impact and imparts an visceo-elastic quality to the device. If iBall is dropped, it reverses it's trajectory upon hitting a solid object and can return to your hand. iBall can survive 40 foot falls with no damage.
iBall also incorporates our newest technology, called "Play-Time". When two or more iBall users meet, spontaneous gaming may ensue. Two games are included with your iBall purchase, including "Catch" and "Soccer". Further game apps are being developed and will be released through the App Store."
