Query: Windows Vista Ultimate Upgrade (to Windows XP Pro, SP2)

I chose the installation option that preserved all my settings in Windows XP Pro. The installation was uneventful, except for the duration of over 3 hours. Installation duration and feedback to user during the installation are below par, especially when compared to those of Mac OS 10 Tiger.Start-up duration and functionality are better than those of Windows XP Pro, as is the user interface.
