It was for me. I would plug my Note 2 into my iMac and...nothing. It wouldnt even come up as a USB device since Samsung wants to force you into using Kies, which is awful. I plug my iPhone 5 into my iMac and iTunes opens to back everything up, sync my music, apps etc...iPhoto will open up so I can download my photos and videos and I still have photo stream sending my iPhone pics to my Macs and iPad. Its worlds easier to use an iPhone with Apple products, have to jump thru a ton of hoops with an Android phone and a Mac.
Point taken - I've only had Nexus so never had to worry about Kies, Samsung does make it harder I believe. But IIRC HTC has syncing software that's iTunes/Mac friendly for converts, maybe someone with a One can confirm.
