INTRODUCTION Formed on February 15,2010. Jointly found by two pillars Intel and Nokia by joining their existing open source projects Moblin and Maemo. Hosted by Linux Foundation. MeeGo is a Linux-based platform that is capable of running on multiple computing devices, including handsets, netbooks, tablets, connected TVs and in- vehicle infotainment systems.

MeeGo ? MeeGo=Best of Moblin + Best of Maemo One OS – Many UX A fully open source software platform Supports multiple hardware architecture (IA and ARM) The core OS up to UI libraries and tools Reference user experience and applications Standard set of API and a SDK Easy to use, flexible & powerful Supports a magnitude of mobile client devices Delivers best web experiences

HOW DOES THE PROCESS WORK ? Upstream Projects Patches and drivers must be submitted to the appropriate upstream projects Hardware Vendor

SOFTWARE PLATFORM BENEFITS MeeGo Software Platform benefits to: Open Source Developers Application Developers Device Manufacturers Operators Linux Platform

Open Source Developers: MeeGo = a true open source project Hosted by the Linux Foundation Governed by best practices of open source development Access to tools, mailing lists, discussion forums Full access to technical meetings Source code contributions are driven to upstream projects

Application Developers: A single set of APIs across client devices Support for app deployment across multiple device types Availability of a complete set of development Ability to easily and rapidly create and deploy apps Possibility to host apps in different app stores

Device Manufacturers: Accelerated time to market Optimized software stack Support for multiple architectures Lowered complexities to target multiple device types Ability to participate in the evolution of the software platform

Operators: Differentiation through user interface customization A single platform for multitude of devices Familiar experience for subscribers using different device types

Linux Platform: Contributions and technical work driven to upstream projects Combines mobile development resources towards a unified platform Cross-platform, cross-device and cross- architecture development Other Linux mobile & desktop efforts will benefit
