I hardly ever watch product videos. I'm usually in locations where It would be rude and I don't want to put in earphones just to find out what's going on. But I'm a curmudgeon, and may be an outlier.
I will happily join you in outlier-land. I want to be able to read - and quickly grok - what a product is about. Needing to watch a video to understand a product is a marketing fail, IMO.
I'd join that too. I never liked videos that are just some person reading from a script. Just give me the script, I'd rather read it at my own pace and time, and I don't care if you really want to be youtube-famous.
