I managed to get an offer for Windows 7 Professional for £30 (as a download only version - it is available to all people who are "students" or teachers or have access to an email address ending in .sch.uk or .ac.uk and a few others too) and since my Vista installation was both slow and the install of Vista Service Pack two was constantly failing, I thought it would be a good offer to waste the money. I did and this post is being written from Windows 7 Professional.
