Windows 8 Developer Preview

I just installed the Developer Preview of Windows 8 and discovered it has a similar "one account, login everywhere" approach as Google Chrome OS. Anyone familiar with Chrome OS will know that logging in with your Google Account brings over all your settings, so any Chrome OS computer becomes your personal computer. Well it seems like Microsoft has taken this approach with Windows 8 (login with a Windows Live ID). I think this is a good approach to take, as it makes it easier to upgrade to a newer computer in the future.
