For those keeping scores at home that display comes up just 100 lines short of the resolution on Apple's iPhone 4, which has a 960 x 640 pixel display, and because the Motorola Atrix 4G screen is a bit larger it also doesn’t pack the same pixel density. Still, it the gets the title of being the first dual-core processor on AT&T's network and has little to envy on the features front – dual cameras, expandable storage through miniSD cards, HDMI-out, and HSPA+ "4G" connectivity.
But perhaps the coolest feature is the Atrix's docking ability. Motorola showed off two different docking stations that allow its smartphone to act like a full-blown computer: The first is a laptop-sized expansion dock, which is essentially a brainless 11.6-inch, 2.4lb laptop complete with keyboard and trackpad, while the HD multimedia dock features a power connector, three USB ports, and an HDMI output to hook up a monitor and peripherals.
Both docks use a special “Webtop” app that enables PC-like features such as a windowed UI, an application dock, a full desktop version of Firefox 3.6 with Flash 10.1 support, a file manager, support for your mobile apps on a big display, and Citrix remote desktop support which Motorola showed connected to a PC running Windows XP full screen.
