Joel of Joel on Software has a good read on choices = headaches as he examines the new Vista shutdown options which give you 9 different menu options to choose from as you walk away from your computer. He also goes into how choices suck and actually restrict you more (ie: notice how in the open source world there are probably 50 different distros out there, and only maybe 5 of them are "real" choices; and while there are probably 10 different window manager / desktop environments, you really only ever choose between GNOME and KDE). I also like how he takes those 9 choices for shutdown and manages to combine them down to.... well, I'll let you read the article yourself.
