Windows: If you're eager to give Windows 8 a spin, you'll get your chance starting at 1pm AEST, when Microsoft will make the Windows 8 preview available as an ISO download on their developer website.
You can opt for a 32-bit or 64-bit x86 build; developer tools will be optional.
PCWorld reports that because this is a pre-release code, not a beta release, a clean install is required.
Here's what Windows 8 looks like so far. Will you be giving it an early try?
