MeeGo is much broader than Nokia participation. Among others Intel is a major actor.
From the quoted article:
"MeeGo takes a different approach, aiming to be a vendor-neutral Linux platform for a variety of devices"
"MeeGo is a different creature in the realm of Linux. In some respects, it is much like any other Linux distro focusing on packaging, integration, building and supporting releases, and helping third-party developers. But in other respects it is very unusual; something like a "metadistribution" because it ships multiple UXes designed for different types of hardware, but it also expects customers to take its code and modify it heavily before delivering it to consumers. Once you dig into the project, however, you can see that it's just Linux underneath although the opportunity it offers app developers to write open source programs for netbooks, phones, and other devices is certainly new territory."
