If you're torn between the Apple Watch and Android Wear then Corbin Davenport may have the answer for you... a Google smartwatch running Apple software.
Although, this probably isn't the hack you're imagining. It's not Watch OS running on Davenport's modded Samsung Gear Live; it's Mac OS. We're not talking Yosemite, we're talking about the Apple software you'd have found on a Macintosh II in 1991.
Davenport, who has previously hacked Windows 95 and Minecraft to run on Android Wear, used the Mini vMac emulation package for his latest wacky mod-job.
As with his previous hacking examples, it's best not to ask why, or to criticise the usefulness of his efforts; rather sit back and enjoy some absolutely pointless but impressive handiwork.
