So today I tried to get a photo from my wifes iPhone to my MBP. Selected the photo and "share", and saw AirDrop. Awesome I thought, finally I get to use this... didn't work. Apparently it only does iOS to iOS or OSX to OSX. How useful.
OK, next I thought, both devices have Bluetooth, so it should be easy to connect and exchange a file... again, no luck. Before wasting more time, I sent it by email, all the way to a server in the US and back, because apparently that is the easiest way to get a file from an iPhone to a Mac in the same room.
So much for the benefits of the Apple ecosystem. I'm not saying that Google or anyone else is doing it better, just that in practice there is little benefit from having both Phone and laptop from Apple.
I use Dropbox and Google services instead to keep my important data, email and calendars synced across multiple devices and platforms.
Oh and I see iMessage being mentioned: In a world with WhatsApp and Hangouts, why would you use an App that only allows you to chat with your iPhone friends?
