Walter Mossberg has kind of a lukewarm review of Motorola's Atrix 4G smart phone. He only mentions the iPhone 4 once, saying the Atrix screen is good but not quite as good as the iPhone retina display. The laptop dock doesn't make the grade, he says:
But the combination of the phone and dock wasn’t as fast, smooth or versatile as having a real laptop, even though to use them you’re essentially carrying around a light laptop (the dock weighs 2.4 pounds). Many apps on the phone aren’t as polished or powerful as typical PC apps, and I found them clumsier to use with the keyboard and touch pad, as opposed to the touch screen for which they were designed.
