First up, meet BlinkFeed, the jewel in the HTC One's software crown. This Flipboard-style app makes a mosaic of news stories and social updates on the phone's home screen. It looks good, and if you keep scrolling down, new stories will appear.
You choose what populates your BlinkFeed home screen. You can choose from a selection of news sources (including CNET, natch), or select topics you're interested in, likes games or music. BlinkFeed also shows photos from your phone's gallery.
...Because this is the new multitasking menu, conjured by double-tapping the Home button. Hold the Home key down for a moment, and you'll be taken to Google Search. That's more functions from one button.
