Microsoft Designing Midori, Windows' Replacement

Microsoft is working on a new operating system that could potentially replace Windows.Midori is being designed from scratch to support Internet-based computing and multicore architectures -- neither of which the company thinks can be addressed by evolving Windows. Microsoft isn't discussing the project, but company research documents confirm it exists; according to those documents, Midori?s proposed design is Internet-centric and predicated on the prevalence of connected systems. The OS -- an offshoot of Microsoft Research?s Singularity OS, whose tools and libraries are completely managed code -- was also described as "OS in managed code," paving the way for cloud computing.

Microsoft intends to let Midori applications co-exist with and interoperate with existing Windows applications, as well as to provide a migration path.SD Times, InformationWeek
