Apple Adds iCloud Safari Tab Syncing to OS X Mountain Lion Preview 2

One feature promised in OS X Mountain Lion was the ability to sync Safari tabs between different devices. Macworld reported it in their Mountain Lion Preview, but was unable to actually find the feature in their early build.

And although I couldn’t find this feature in the version I tested, Apple says that Mountain Lion will bring the ability to sync Safari tabs to iCloud, so your open browser tabs can sync between Macs.

The features seems to be now implemented in the Developer Preview 2 that was released tonight. We received this screenshot which shows the feature button in Safari:

The feature is believed to sync open tabs between Macs and iOS devices, providing you with a relatively seamless browsing experience across devices.

Update: Here's an image of it working across two Macs.

I hope I can turn that off. They shouldn't put it on the taskbar, let it be a preferences thing. Clunking up my browser.
Hold command and drag it out if you don't want it.

This is a pretty cool feature :) Hopefully third parties will have access to the API such as Atomic Web and Terra. :cool:

How would this work? iPad's Safari has a maximum number of 9 tabs, while Mac's Safari can have as many tabs as needed.

I'd settle for Apple re-implementing accessing bookmarks from remote computers; a function that was lost with the demise of dot mac.
This is possible in iCloud, on all of your devices, today.
