Inexpensive, compact netbooks were all the rage during the recent economic downturn, and the product segment enjoyed explosive growth over that period. However, that growth rate started falling heavily at the end of 2009; in April 2010, netbook sales only grew a mere 5 percent. Morgan Stanley analyst Katy Huberty says the iPad is to blame for the stalled growth, but it seems more likely that netbooks have merely saturated their niche in the market. - Bonnie Foster
