Unless you’ve been wearing earplugs and covering your ears for the last few hours, you’re likely aware that Microsoft finally took the wraps off Windows 8 today, and promised that a developer preview would be released today as well. Best of all, it’s accessible to everyone, not just developers.
Download the .iso and info here it's freeware for all to try out
(the 32bit .iso is reported 2.8GB!)

Looks interesting as it says it will run on any Win 7 spec machine. A little project for me at the weekend I think but not sure at this stage if it will dual boot and also the USB install does not appear to run from the stick but requires a full install to the hdd.
Further research is required......
