At the leading edge of this new wave of dual-core superphones is the Motorola Atrix. One of the major innovations of this device, besides the next-level processing power and fingerprint scanner, is Webtop - the desktop-style interface available when the Atrix is docked. By plugging into the HD multimedia or laptop dock (sold separately of course), you can interact with the phone on a larger display while using an internet browser, file explorer and Facebook in a pseudo-desktop environment.
While the feature is pretty nifty, the price tag isn't. The cost of the docks may have come down since the release of the Atrix, but $400 for the laptop version is still prohibitively expensive for some.
