Google's (NASDAQ:GOOG) $12.5 billion acquisition of Motorola Mobility (NYSE:MMI) is on track to close sometime in the first half of the year, and Motorola's Webtop software may be one of the key pieces of Motorola's business that Google will get. The software, when paired with laptop-like docks that connect to Motorola's smartphones, enables a desktop-like computing and Web browsing experience via smartphones. CNET and its sister site TechRepublic took an in-depth look at how Webtop was created inside Motorola and how Google could leverage it as it moves forward. The article looks at how AT&T Mobility (NYSE:T) pushed Motorola to develop Webtop commercially to be paired with its Atrix smartphone, and the early missteps Webtop had. The bigger questions are what Google will do with Webtop, how it will integrate it with Android and if Webtop can help Google combat Apple (NASDAQ:AAPL) and Microsoft (NASDAQ:MSFT) in mobile computing.
