There have been talks of Apple filing for new patents and the rumor of the smaller and cheaper iPad, the new iPhone and the Verizon Apple deal. The other included filing for patents to take action against the Jailbroken iPhones. Today PatentlyApple has released schematics of what can possibly be the upcoming iMac Touch.
From the diagrams it appears that the new iMac will be usable as both the desktops machine when in the upright mode or the OS X mode as more commonly referred. When slanted, it switches functionality and acts a touch pad and operates in the iOS mode. The other addition is the more flexil0 adjustable stand that helps in easily slanting the iMac.
I will leave you with the images for now and return with a bit detailed followup later.
Thanks Patently Apple
