Although we all knew it would happen, original equipment manufacturers (OEMs) like Dell haven’t said much about how they will use Windows 7, I guess because it wasn’t offically out yet, but now that Windows 7 has been released OEMs are starting to move all their products over to the new version of Windows. Dell has announced that they now have 80 models of computer from the 10-inch Inspiron Mini 10 netbook to the ultra-powerful Dell Precision T7500 workstation that ship with Microsoft Windows 7 pre-installed.
