Much like the Developer Preview released last September, the Consumer Preview is to be a free download
for anyone willing to try it out on a "testbed" PC or in a virtual machine. As it's classed as a public beta,
it isn't generally recommended to install it natively on your main (or only) PC, although that's entirely
up to you to decide. With a bit of common sense, and keeping relevant data backups, you shouldn't
have much of a problem, especially if this is as stable as the Windows 7 public beta was.
