Believe it, man.
A pro will have multiple windows, tabs, text files, audio files, skype calls, all open at the same time, on up to 4 monitors.
They'll save every 5 minutes; then,
they'll save every 10.
They'll save every 10 minutes; then,
the'll save every 10 days.
They'll save every 10 days; then,
Blue Screen of Death occurs; then...
"wtf? what happened to all of my files?!".
If not a BSoD, then some other OS-specific disaster, equal in magnitude to a Blue Screen of Death.
Don't let it happen to you.
