Cellular MacBook Pro
Back in 2007, Apple was working on a cellular version of the MacBook Pro. Obviously, this was never released, but there is evidence of its existence. In 2011, one of the prototypes of this MacBook Pro showed up for sale on eBay. The seller stated they got the device on Craigslist as a “for parts only” sale. With an antenna built into the display and a SIM card slot on the logic board, there is no doubt that Apple was seriously considering the device for market release. However, Apple has remained silent about it all these years later.
