you'll be pleased to know that Yosemite and iOS8 are gonna sync tabs and history between mac and idevices when they finally come out.
Been able to share Safari Tabs on Macs for years now since Mac OS 10.8 and iOS 6 and it's free. Of course, been able to also share Tabs other ways as well even longer, but you mentioned Safari.
I'm guessing you're an iOS user?
Suxors if you use Safari (why do you use Safari?)
If you want to share your Safari tabs with your Mac OS X computer and iOS device, there's iCloud Tabs which has been around for years.
For sharing links, I use Pocket with Safari, there's also Cloudapp, etc. and both work across my Andriod, Windows and Mac devices flawlessly and they're free (for basic usage).
It's also one less way for Google to not watch one's every, single move no matter what you do online.
Of course, Firefox also shares Tabs which I use occasionally to share tabs between one of my Android devices and my Macs. And Android Firefox (with its superior add-on support) is vastly better than Chrome when it comes to privacy, extensibility, customizations, compatibility, etc. on Android.
I also should mention that Safari on Macs has superior extensions compared to Google Chrome on Macs. But, of course, for stuff within Google's walled garden, it's necessary to keep a copy of Chromium and/or Chrome on the machine as well.
