Alfred is a great app launcher for mac users that uses spotlight search and web search to get you almost anywhere with a quick keyboard shortcut. I have not found any application for windows that does as good of a job as Alfred with application launching and file and web searches. Is there an application like Alfred for Windows, if there is not, should there be?
Windows 8 has Bing search, lol. Most Linux distros have had that ability for a while, though.
