I said that for my first, and did it for a while. And because I prefer to use ITunes for my back-ups, it only happens every couple of weeks now. But, I have contacts on iCloud (as well photos, calendar, reminders and find my iPhone) so that those are automatically up to date and recoverable from iCloud. We all develop the method that works best for us. I will admit, I would back up to iTunes more often if I turned my computer on more often but I pretty much have replaced the computer with the iPhone so my laptop sits idle and unused.
