ComputerWorld published an in-depth review of the pre-beta version of Windows 7 and claims the upcoming operating system shows great promise. The reporter says there are no massive changes, but the OS is more functional, more efficient and provides a better user experience than Vista.
Windows 7 is in pre-beta, so there's no way to come to a definitive, bottom-line conclusion about the operating system. However, it's surprisingly stable, solid, well-done and speedy at this early stage in the development cycle. Some important features of it are still missing -- notably, the new Taskbar.
However, even at this early stage, it's clear that Windows 7 is a real improvement over Windows Vista. It cleans up some of Vista's rough edges, adds useful new capabilities and most likely won't have the same problems with hardware that Vista did. We'll have to wait for further betas to offer a more definitive conclusion.
