None of these comments has mentioned my two pet hates. (1) Tiny little windows for changing system settings - for example the XP "wireless network connection properties" and in particular the scroll box headed "this connection uses the following items" and (2) The need to go to several different tiny windows to get at all the related settings - for example some of the wireless settings require you to go to the "device manager" window. When people want to change settings they rarely need to see another part of the application, so why not put all the settings together on a full-size screen? Having said that, in the particular case of wifi I have learned through bitter experience that it works best if I don't fiddle with it - apart from changing the "obtain an IP address automatically". But even that requires stepping through 4 windows.
