Wolfram Alpha app (US$2.99) fans should be rejoicing today. Version 1.4 of the incredibly powerful analytics app is available and adds a number of new features, including image analysis and manipulation.
Among the new goodies in Wolfram Alpha 1.4 are a new look for weather queries and the ability to search for and purchase items from Best Buy. Yep, that last feature is correct. You can now query Wolfram for things like "17 inch LCD monitor" or "LG Washing Machine" and get more information than you really ever wanted -- plus the ability to buy those items from the app.
