I like to use tabs when I program. I like that I can be editing the same file in a network drive with my tiny screen and have my editor there show a tab as two spaces and my big screen where it shows as four. I like that when I'm screen sharing I can zoom in and bump my font size, then set the tabs to render as smaller so I don't need to run reindent on the whole file. I like that when I'm using a boring IDE with no customization it just inserts an indentation.

I also hate auto-closing parentheses and brackets.
