With its new set of powerful tools and technologies, WES7 is a dramatic improvement over its predecessors, especially given the degree of customization and flexibility that it offers in regards to image configuration and building. WES7 delivers the power and reliability of the Windows 7 operating systems, while also providing the essential features of an embedded operating system - componentization and customization. The focus has been to reduce time to market by enabling OEM developers to spend more time on their core competency of application development and less time figuring out the correct set of components required to build a fully-functional image. Although WES7 lacks a few features which were available with its predecessors, overall it is a sleek embedded operating system. There is definitely a significant learning curve in transitioning to WES7, but the benefits far outweigh the costs.
