7 is running fine on both my laptop and my desktop (depicted).
The desktop did have a driver failure during 7 install, but it appears to basically work. Still, it's a bit sad that "self-healing" doesn't really account for this. The most fundamental kind of healing, it would seem, would be to ensure all system files are present. But so far no big deal - it's only Sticky Notes that complains over a missing Ink dll.
