We argued in this space over five months ago that the justification for a mongo market cap was bigger than just web search and advertising. Google is positioning to
dethrone Microsoft as the center of the universe.
Ten days later we argued that Google's desktop search could be its toehold in on the desktop that Google uses to "leapfrog and marginalize Microsoft, usher in a new era of network-centric computing, and make Microsoft's core operating system monopoly
largely irrelevant."
If you buy that, then maybe Google's worth much, much more than today's $142/share.
See for yourself. Google released their Desktop Search tool today. It downloads and installs fast. Uses the simple and easy Google interface. Returns results in less than a tenth of a second (compared to minutes for Microsoft). Provides relevant results -- not just meaningless file names. And it finds Outlook email right along with Word, Excel, and Powerpoint documents.
Nothing short of awesome.
