Space on RT

Justin Rubio:

Microsoft has revealed exactly how much free space new Surface owners are left with after taking into account Windows RT and system-related files. For the 32GB version of the new tablet, users have access to only 16GB of storage, with the remaining half taken up by Windows recovery tools, Windows RT, Microsoft Office, and built-in apps.

What's most amazing about this to me is that this is the stripped-down version of Windows designed exclusively for tablets. How unreal will the space requirements for Windows for Surface Pro be!?
