GMGruman writes: About 100 Android tablets and smartphones have been shown at the CES 2011 show this week in Las Vegas. But most — like PCs — are clones of each other. But five devices announced at the consumer show stand out for innovation and could propel the Android platform even further in its competition with Apple's iPhone and iPad: Motorola's Atrix and Xoom, Samsung's Infuse 4G, Asus' Eee Pad Slider, and Vizio's Via Phone. The Atrix also represents a step to the post-PC future. CES this year served as the coming-out pary for 4G networks, though as Galen Gruman blogs, don't expect widespread 4G availability for years yet.
