bing.com – new travel tool?

bing.com (a MS venture) is being advertised on TV alot. I am working on my fall trip so I went to kayak.com as usual and then to bing.com and bing is doing the same thing as kayak (checking all internet deals). The feature on TV is a price predictor. The price predictor has limitations when using for flights outside the USA. So, for those of us flying across big ponds, its value is no more than kayak. I’m stickin with kayak.
