4G is here - and it seems like all four of America's biggest carriers are more than happy to advertise the fact that they've got it. Sprint was first on the scene - offering their WiMax 4G, and T-Mobile shortly thereafter began its upgrade to HSPA+ technology. Verizon was next, providing mobile broadband LTE via USB dongle for laptops, though its much-awaited debut 4G handset, the Thunderbolt, has yet to hit shelves after numerous delays. Finally, lagging behind in truly characteristic fashion, AT&T has begun to roll out its own HSPA+ network, with plans to offer LTE in the second half of the year.

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.
