Hewlett-Packard’s latest teaser video for its upcoming “slate device” is clearly designed to highlight some of the biggest complaints about Apple’s new device. Among other things, the HP video shows the ability to take a picture with the HP slate, and access media and devices via built-in SD and USB ports. “Think about the last time you chatted with friends over Skype on your notebook. Or uploaded a picture from your mobile phone to Facebook or Flickr,” the company writes. “How about the last time you viewed images or video from an SD card or a USB device. We know that you expect to be able to capture and share digital content on your mobile devices. And the HP slate device excels there.” The USB cable looks remarkably like a Apple USB cable.
