At the end of last week I rebuilt my main Toshiba M3 notebook using Windows Vista RC1 and the Office 2007 Beta 2 Technical Refresh. Overall impression - great stuff! A big improvement over Vista Beta 2 - it feels slick, responsive and finished. Certainly easily capable of being my main machine. Currently I have only experienced one problem - the mouse pointer vanished after a restore from sleep. Turning on mouse trails on control panel brought it back! Quite amusing really as the mouse pointer was there - just not visible on the screen.
