The idea is a Windows 10 tablet can double as a mouse while it's hooked up to an external monitor or TV. While it may seem like a niche use case, it means anyone wanting to use their slate like a proper PC can carry one less peripheral with them -- assuming it performs the task well enough. The virtual trackpad comes to Windows 10 alongside updates to Microsoft's Sticky Notes and Windows Ink Workspace software, and you can take it for a spin right now provided you're in the Insider program's Fast Ring.
