As Paul posted, Microsoft is adding the Start Screen to the list of features synchronized between your Windows PCs.
But that's not the only addition.
Rummaging around in the registry reveals a heap of new additions, a couple of which I'll cover briefly below.
Internet Explorer Tracking Protection and tabs
Internet Explorer will be syncing its tab and Tracking Protection configuration to the cloud, allowing you to take your browser experience on the go -- perhaps with, say, Windows Phone?
Pairing your laptop with a device, say a Bluetooth keyboard, can be a surprisingly onorous task. But "Blue" will only require you do this once, syncing the association with the cloud and enabling you to move your devices to and from your PCs with ease.
Other synchronized items include:
- Picture Password
- File History
- Input Personalization
- Explorer Quick Links
- App Secondary Tiles
- Installed Apps
