Personally, I'm all for anything that improves the context of recommendations - if I can spend less time telling a computer/phone/tablet what I want, and more time being served up with relevant and interesting results, that strikes me as a good thing!

Google Now has been doing this for a little while now for UPS tracking numbers and some other information that comes in through email. I think it is overall a good feature but it also has some concerns obviously, but you can always turn it off if you don't want Google to be using this information to display other related content to you. As long as they keep privacy in mind, I'm all for it.
