Do you want a virtual assistant on your desktop?

Microsoft showed off a number of new features from its upcoming Windows 10 yesterday. It brings support for things like universal apps, a new and improved web browser, potentially free upgrades, cross-platform gaming and more. One of the more interesting announcements was that Cortana, a voice-controlled virtual assistant similar to Apple's Siri and Google Now, would be available on your desktop. Many of us spend our days in office environments, where it's not convenient to talk to our computers (besides, I have other issues with virtual assistants as well). Is this something you'll find useful on your computer? Head over to the Engadget forums and let us know what you think.
