I totally disagree, the back button is the single greatest UI improvement of the web. There are a lot of non tech savvy people out there who are so afraid of breaking things that they won't even open context menus in Word without saving their document first. All of those use facebook and the web like champs because they can never totally screw up because the back button takes them to safety. Don't forget, many grew up during times when using technology wrong meant that you would loose an arm. Back button fixes that anxiety.
