Please allow me to disagree. I think that the MAC option gives you more flexibility. You can separate the text editor box and the text formatting palette by setting
"jump to preferred position"
instead of
"above text editor"
for the formatting palette in
"Work Environment/User preferences scheme/Dialog Boxes & Palettes"
So you can drag around the formatting palette without resetting the text input box. But in some cases you might want to drag the text editor box too, e.g. you want to see what is underneath, or you want it to put it in the middle of the screen for better visibility, etc. These are things you cannot do on PC.
