It's not useful if you use it to auto complete pages of code. It is useful to see it propose lines, read, and accept its proposals. Sometimes it just saves you a second of typing. Sometimes it makes a suggestion that causes you to update what you wanted to do. Sometimes it proposes useless stuff. On the whole, I really like it and think it's a boon to productivity.
