Have to agree with Toby on Vista and Office 2007. There could not have been usability testing. The menus in Office 07 have all changed. Try and add a worksheet in Excel - the option isn't under Insert or the windows icon - you have to search for it, of course why would you want to add a sheet? And if you use any object in PowerPoint you will be informed, even though the same squares and circles were available in all previous versions, that it is no longer compatible with older versions, nope, cause now they are Smart Art - yep. And time yourself on how long it takes you to find the "Change Shape" option. Now Word - ah the bane of my existence - I still haven't figured out what they heck they've done to styles - oh and speaking of which - try and set a global footer in PPT - let me know how that works for you. And Office 2007 is NOT compatible with any version of Acrobat prior to 8. You get error messages up the wazoo. As for crashing and slowness - it compounds - the first day I installed Office 2007 on my new Vista loaded laptop I "froze" 5 times. It gets better, my machine only locks up about once a day. But I know my boss understands...right Toby?
