I use a desktop at work, have a home machine, a laptop for trips and the tablet for on the run stuff. So does this mean 4 licences? I use only one machine at a time, and does seem absurd to licence the box rather than the user. What happens when I start up a trial virtual machine? Do all VMs need licencing too?
(BTW - don't knock Win8 - you're sounding like the old Win95 knockers)
