Chromebooks to enterprise and education customers under a subscription model. What's not clear is how much of a splash it actually made in those markets. While the notion of paying a monthly fee for three years, instead of buying a machine up front sounds like a game changer, some people just like the comfort of the familiar. To that end Google is now offering those same customers the option to purchase a Chromebook (with a year of support included) in one lump sum -- $449 for the WiFi model or $519 for the 3G to educational customers, while business are looking at $559 and $639 respectively. After that first year is through, customers have the option to sign up for a monthly support contract, at $5 a month for education and $13 a month for enterprise.
