We get HP6300's with W8 stickers but W7 pro on them from CDW. I don't image mostly because it doesn't work too well with AutoCAD. We have NO PLANS to "upgrade" to W8. Hell, I'm still prying the last few XP boxes out of cold dead fingers. I only load maybe 2-3 a week so it's not much of a problem. We still use the XP VMs a lot for accessing data from various aerospace partners. Each one seems to need it's own specific version of IE with just the right settings and plug-ins.
But yeah, 8 ain't going to fly here, now with dual screen workstations and AutoCAD.
