MS v/s Silicon valley
For a long time now i've thinking to map Micorsoft's competition.
But everytime i started writing about it, every single company in silicon valley came up.
Now Om Malik has taken some pain and counted all the companies and put them in a nice image for u which is aptly titled "Microsoft Versus Silicon Valley".
Though not all of them belong to the silicon valley but u can take silicon valley as a general term for all the tech companies.
