I tried it and was disappointed. For example search Wolfram Alpha for "Abraham Lincon's Height" and it won't be able to figure it out. Search Google, and it will be parsed out nicely at the top of the page, no wading through search results necessary.
Same here. Based on the demo video, I thought a natural language query about some oft repeated numbers - 'Web browser market share by year' would be doable. It wasn't.
