Your favorite tiny feature?
gkoberger: Windows 7 had a ton of these:  - Dragging to the side/top of the screen
  - Being able to drag a window away from the top of the screen without minimizing it first
  - Preview of windows when running your mouse over the task bar
  - Desktop slideshow
  - Progress bar in task bar (http://rurl.org/28nt)
  - Functions built into the task bar (for example, you can see controls for iTunes by just mousing over it in the task bar)
  - Snipping Tool

I'm sure there's a few features I missed because I take them for granted now- but I remember being amazed by the little things.
