I have started messing around with Windows 8 Consumer Preview recently. I installed it on a VM using Virtual Box. Its quite straight forward, and it worked quite well in a VM. It can be unstable to start with, needing a few restarts to boot, but once booted, its quite stable, and it works well.
The question to me is, is it worth upgrading? As it stands, I don’t think so. I am not going to upgrade because to me it seems more like a stripped down version of Windows. There are severe limitations when using the desktop version, and all the apps don’t really add any value. It just seems to limit the functionality. I can’t imagine any business upgrading to Windows 8, considering that Windows 7 is so stable, reliable, and easy to use.
Overall, Windows 8 has not been the change I was expecting to see. I am hoping the final release version would be better in terms of offering users the choice between using the Metro Start Screen and the Windows 7 start menu. Of course, there is also the possibility that the metro interface is going to be a huge hit among consumers, and one day will be look back at the time when we complained about it. Only time will tell.
