I prefer simple text or PDF myself. Our corporate policy is to avoid 'frivolous' use of streaming video and other high-bandwidth use. While this article can be considered work-related, I prefer to avoid unnecessary conflict as watching videos is deemed 'unproductive'.

Unless something is being demonstrated that really requires video, I prefer to save articles and read them during breaks/down time. I can also skim through them and determine how appropriate and useful they are.
