Ubuntu Netbook Edition, especially, will cease to exist and will be merged under the same Ubuntu brand name, just like all other variants. This decision comes after increased demand for Ubuntu on portable devices, mainly netbooks. The existence of a Netbook Edition would make users assume that the standard Ubuntu edition isn't good or optmisied enough for netbooks. "The introduction of the new shell for Ubuntu means that we have a user interface that works equally well whatever the form factor of the PC," said Canonical while explaining the dissolution of Ubuntu Netbook Edition.
Since the Ubuntu 11.04 onwards will be multiplatform and optimised for all devices - desktop and portable - it will be distributed as a multi-platform solution that's advertised to work well whether you're using a netbook, laptop or a full-fledged desktop. The Ubuntu distro is expected to hit the Internet by the end of April.
