Run Windows 8 on USB-memory stick

It's possible to run Windows 8 on USB-memory stick. Microsoft has a name for it: Windows To Go.

Ok, how to prepare Windows 8 on USB-memory stick? First off, you need these:

• A PC running Windows 7 or Windows 8
• The ISO image of Windows 8
• The Windows Automated Installation Kit (AIK)
• A USB storage device (at least 30GB) 

Then follow steps at Ars Technica: http://arstechnica.com/business/2012/03/ordering-windows-to-go-how-to-create-a-bootable-windows-8-usb-thumb-drive/

Will this kind of way of using Windows be very popular? I have no idea. It might be handy for support people. Security enterprises like F-secure benefit from it since "all bad things are transmitted via Windows To Go -sticks".
