Within the start bar you also have the live tiles. You might be familiar with this if you remember it from Windows 8 when you had the full screen live tiles. Now they've included them within the start bar and you can re-size and move them around to your heart's content and fortunately you don't have to go completely full screen tablet mode to use them.
To add to this feature they've also included task view which is a lot like Mission control or Expose if you're used to that in the Mac World which basically just gives you multiple desktops which is really useful if you're using this on something with a smaller, lower res screen like a laptop.
The general rule of thumb is every other Windows is a good one and Windows 8 wasn't great so it must mean this one's good. And if you get it within the first year Windows 10 is free!
