MeeGo is a Linux-based open source mobile operating system project.[2] Primarily targeted at mobile devices and information appliances in theconsumer electronics market, MeeGo is designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV,IPTV-boxes, smart phones, and other embedded systems.[3] MeeGo is today hosted by the Linux Foundation.[4]
It was first announced at Mobile World Congress in February 2010 by Intel and Nokia in a joint press conference. The stated aim is to merge the efforts of Intel's Moblin and Nokia's Maemo former projects into one new common project. According to Intel, MeeGo was developed because Microsoft did not offer comprehensive Windows 7 support for the Atom processor.[5] Novell also plays a large part in the MeeGo effort, working with the Linux Foundation on their build infrastructure and official MeeGo products, and MeeGo is increasingly using more of Novell's technology that was originally developed for openSUSE, (including openSUSE Build Service, ZYpp for package management, and other system management tools).[3][6] In November 2010, AMD also joined the alliance of companies that are actively developing MeeGo.[7]
Harmattan, originally slated to become Maemo 6, is now considered to be a MeeGo instance (though not a MeeGo product), and Nokia is giving up the Maemo branding for Harmattan and beyond (Maemo 5, aka Fremantle, and previous versions will still be referred to as Maemo).[8]
In February 2011 Nokia announced a partnership with Microsoft for mobile handsets[9] and the departure of Nokia's MeeGo team manager Alberto Torres,[10] leading to speculation as to Nokia's future participation in MeeGo development.
