A few months ago I installed a 'release preview' version of Windows 8 onto a computer in our office. I must admit that - at the time - I was rather disappointed. After around an hour of using it I had decided that it was not for me and probably not for our clients. For one, the 'Metro' interface seemed entirely suited to touchscreen tablets and a second issue was that I couldn't even find the shut down button - it's well hidden!
At time of writing though, things have changed.
Windows 8 has still not been released officially, but as Microsoft TechNet subscribers we have been able to get our hands on the release version of Windows 8 earlier than most people.
I took the plunge about three weeks ago and have installed Windows 8 Professional on one of our home computers, and on my primary laptop. I'm very happy with the results. I have used the Windows 8 laptop every day for work and am extremely impressed with the stability of Windows 8.
The 'Metro' interface has been renamed 'ModernUI' (indicating the new start screen style is here to stay). The new start screen is very different, but isn't cumbersome in the slightest and does not get in the way of the more traditional Windows 7 style interface which most people are used to.
It's one of the only operating systems that Microsoft have ever produced that I'd be happy to install for a client on the day it is released. Given that I've been working on every version of Windows since Windows 3.1, then that's a big deal.
