Airdrop iOS / OS X

Am I the only one that thinks it's ridiculous that you can't Airdrop between iOS and OS X? The 'Airdrop' name is used on both operating systems, yet they can't be used cross-platform. What the hell? How could this blatantly obvious omission be overlooked?!

Anyone care to shed some light on this?! I haven't seen it mentioned anywhere else on here...
