My first Microsoft operating system was DOS, and after that Windows 3.0. From what I've heard so far about Windows 7, anyone who was using Windows Vista is very happy to upgrade to Windows 7. I've been reasonably happy with Windows XP; it's a stable product. I stuck with XP through the short life of Windows Vista, as did our ILS vendor, which hasn't yet had anything to say about Windows 7 compatibility.
But for once I am looking forward to trying out a new Windows operating system. Windows 7 could solve all my problems with the three wired public computers; they're running Windows XP but, as is so frequently the case these days, we have no media for them. Lenovo has a pretty neat setup by which they store an installable image on the hard drive, accessible only by a key combination and optional password. It provides a time-consuming but reliable recovery for a computer that has been hopelessly compromised by malware. A couple of our public computers have the security password set; I've tried all our standard passwords, but none of them work, so I'm pretty sure a patron must have set it, whether accidentally or deliberately I can't say. Both these machines have problems that make a reinstall necessary, but without media and without the password I can't do much. Buying Windows 7, with the media, solves two problems at once.
