Wolfram Alpha Search Engine Review and Video

Many questions about Wolfram Alpha Search Engine the “Computational Knowledge Engine”, Will it be Google killer? You can not use wolframalpha search engine yet, only “Launching May 2009″ that appear on site.
What can Wolfram Alpha Search Engine do? according to NYT,
” Wolframalpha search engine can describe places, by its vital statistics, such as location, population, weather, etc. It can compare Lexington with Moscow. If you type “LDL 180,” it will tell you the percentile of the population with higher or lower cholesterol and show you the answer on a chart. If you tell “LDL 180 male 45,” it will adjust the chart for gender and age group. It can chart the life expectancy of a male age 40 in Italy or tell you who was president of Brazil in 1928.” Wow….
Here’s the screenshot (Google can do this?)
