Sorry I'm Chinese, and I was on holiday in Florida. What is Bing rewards? I've never heard that before:-o And I found most people around me still preferred Google(when in US not China), with little concern about Bing.Are you in the US? If so, Bing is great for Bing Rewards. I use my Bing Rewards toward Starbucks gift cards, so I rarely need to pay for my coffee at Starbucks.
I mean, if you need convincing, it probably isn't for you. Personally, I just use the search and video and they're both pretty good for me. I just prefer Bing to a) help Cortana become smarter and b) Bing Rewards
Bing is in the red because the ads aren't helping pay for the entire thing. You have to keep in mind that Bing isn't just a search engine, it's a platform. Supposedly, it's suppose to be profitable by next year.
