Chromebooks, and ChromeOS have come a long way, and this year two of the best selling laptops at Amazon are Chromebooks. Computerworld calls it a punch in the gut for Microsoft. "As of late Thursday, the trio retained their lock on the top three places on Amazon's best-selling-laptop list in the order of Acer, Samsung and Asus. Another Acer Chromebook, one that sports 32GB of on-board storage space -- double the 16GB of Acer's lower-priced model -- held the No. 7 spot on the retailer's top 10. Chromebooks' holiday success at Amazon was duplicated elsewhere during the year, according to the NPD Group, which tracked U.S. PC sales to commercial buyers such as businesses, schools, government and other organizations. ... By NPD's tallies, Chromebooks accounted for 21% of all U.S. commercial notebook sales in 2013 through November, and 10% of all computers and tablets. Both shares were up massively from 2012; last year, Chromebooks accounted for an almost-invisible two-tenths of one percent of all computer and tablet sales."
