I am the same way...very hesitant with OS upgrades........although personally I havent really had many issues with IE7...

as for Vista...the hardware requirements alone...I cannot install on a spare to test...and if I did have a spare machine to test on...with those hardware specs...

it wouldnt be my spare

Moira I feel for you...I have had network upgrades that have gone like that...40 hour weekend installs..
