From http://uitrends.com/2009/09/03/command-line-interfaces-dont-... :
command line interfaces are back again, hiding under the name of search
No, they are not. Yes, it's also a box in which you type text, hit return and see results. But a command-line tells a computer to do stuff, a search box tells a computer (Google) to retrieve stuff. By stating that search engines are the new commandline, well, it's not as silly as claiming the web is the new OS, but it's close.
The only reasons I can see why they make these generalizations is either that they don't understand what a commandline does, or it simply brings them more attention. I suspect the latter.
