Apple’s iPad could be set for a design overhaul at some point in the near future. That's because a newly-discovered patent reveals Apple has penned designs for an iPad with an all-glass exterior. Not only does that mean the iPad could swap its metal back for glass, it may not get an iPhone-style metal frame either.
The patent was granted by the U.S. Patent and Trademark Office on Tuesday under the name “Glass Device Housings.” The idea behind this design is to fuse multiple glass pieces together to create the casing, with additional glass added to the edge of each flat surface for additional thickness — and presumably extra strength and durability.
