When learning new technology, do you first read the manual, or attain your learnings from online video?

So you got that new phone, or digital camera for Christmas. How do you learn the feature sets?

Same for other things like software. Are you learning Wordpress, or Photoshop? Do you read the manuals, or watch a video to figure it out?

Ok, this is really about reading vs watching. So if you read to learn, do you read the stock info, or buy a book from a guru expert unaffiliated with the product? Same for video. Do you watch the Adobe approved videos, or the YouTube channel of a Photoshop master (who may show other non adobe products too).
