Google has finally unveiled the Google Now personal assistant service on the desktop through the experimental version of the desktop browser Chrome Canary. Users can access the service by enabling the correct flag (chrome://flags/#enable-google-now) and then relaunching the browser. You will then receive a notice on the Windows system tray or Mac Notification Center once the service has been successfully integrated.
According to the support page, you can see weather, current traffic for commuting, event reminders, and sport scores cards. The other cards like public alerts and nearby photo spots will hopefully be integrated into the desktop version in the future.
