Apple is reportedly planning to switch the Macs used by Apple Store Geniuses to iPads, according to a 9to5Mac report.
Currently, Apple Store Geniuses use MacBook Pros to access GCRM which allows them to check warranty information, repair history, parts availability, and more. Soon, Apple may be supplying its retail stores with iPads that can mirror this functionality.
Apple replacing the stationary MacBook Pros with iPads for Genius Bar functions is a major move that will not only make the Genius' job easier, but provide a much better experience for Apple's customers that are looking for repairs and/or help from the Genius Bar. The MacBook Pros are stationary so they cannot be moved from the Genius Bar. The iPads are portable, so the tablets can allow Geniuses to essentially help customers anywhere in the store. This would open up space at the Genius Bar and allow repairs to be facilitated much more quickly.
The site also notes that Apple is working on a way for customers to sign their signatures on iPads instead of printed paper. This is necessary for authorizing a repair or accepting a replacement device.
Actually they've been using mac book airs for quite some time now but you have the right idea. But that'll only be used for DFU restores. Regular restores will just back up to the cloud, erase phone and restore from
iCloud backup
I don't see that happening anytime soon . Apple devices need USB port for a lot of different functions and iPhone can't be restored with iPad for the moment so unless the start to adding os to the iPad it is not possible
