Microsoft's chatty Cortana is one of the more well-liked parts of Windows Phone, and Lenovo is making it more versatile on its own PCs with ReachIt. It exploits the voice assistant to find your own photos, documents and email across multiple Lenovo Windows 10 PCs, tablets, and even cloud services like OneDrive or Dropbox. The app is personalized with a user-specific Lenovo ID, letting you search for content on, say, your Lenovo laptop remotely from a ThinkPad tablet. It also uses location services, helping you locate a file by making a vague request like "Cortana, find the picture I worked on at Starbucks last week," according to Lenovo.
