Technet anyone???
Just a thought, if your going to be paying €199 for Windows 7 Pro or whatever the conversion to £'s will be then why don't you just purchase a Technet Direct subscription, is about £180/year (cheaper if you can find a 40% discount code).
It will give you access to Windows 7 as well as Office 2007 and plenty of other applications / OS's that you'll probably never use...
