Three days ago I finally removed Vista completely from my system. At present all my computers (3) are running Windows 7 Evaluation (90 Days). One is running Windows Virtual PC RC and XP Mode (XPM RC). Been using Win 7 since November, 2008. Had some problems with drivers, and XP legacy programs, however, since 7600 there has not been a single problem (reason for going with the evaluation version). One of those computers is my new iMac 24" (bought three days ago). Still knotting on wood.
