Well, Microsoft doesn't want to leave the rest of us out of the fun, so they have officially made available an ISO of the Windows Developer Preview. This preview comes in three flavors; a 64-bit English preview with developer tools, a 64-bit English preview (no dev tools), and a 32-bit English preview (no dev tools). This preview can be downloaded right now from the Microsoft Windows Developer Preview downloads page.
So if you are interested in being one of the first to try Windows 8, feel free to give it a try and tell us what you think. Please note that all installs are clean installs and existing installations of Windows cannot be upgraded.
Best part, is you do not need a dedicated machine. Just download and install VirtualBox and test from there.
