The feature's been around since iOS 6. Hasn't worked once for me. Ever. My devices (iPod touch 5th gen and iPad mini with Retina, will be receiving an iPhone 6 later this week) are all connected with the same iCloud account, and all iCloud related features other than iCloud Tabs work fine. I have tried all troubleshooting steps from Apple multiple times over the last several months and have had no luck, I've given up everytime. Is the feature even supposed to work between iDevices or is it only between an iDevice to a Mac and vice versa? Handoff even works flawlessly for me. Could it have something to do with my Apple ID for the iTunes store and App Store being different than my iCloud account? I don't see any reason why that would make any difference, but hey, weird things happen. And yes, Safari is enabled under iCloud settings. Bookmarks, favorites, and reading list all sync just fine. Tabs are also open on both devices.
