The good news: Start Screen syncing is coming to Windows 8 with the Windows Blue update.
Let’s go over what that means. The usual tag-team of Paul Thurrott and Rafael Rivera are out in force, breaking down what is coming next for the Windows platform. Here’s Paul from today:
[W]e were able to test that sync is working simply enough by just signing in to two different PCs with the same Microsoft account. Voila! Start screen sync works: You get the color scheme as before but also the pinned tiles, their individual sizes, and their arrangement.
Rafael went subterranean, peering into the depths of Blue, ferreting out that tab syncing will come to Internet Explorer, and that it will sync device associations, saving you from reconnecting electronics to new PCs. These changes are welcome, and will improve Windows. However, they are absurdly late.
