The problem with tech is its highly monopolistic nature . Every tech sub-sector experiences a short period of chaotic growth and then The One gets chosen to dominate with the praises of the rest of the gang. The lack of competition in the tech sector is astounding on a global scale.
Can you name one of these sectors? Cloud for instance has cutthroat competition. CRM software as well. Mobile phones also have pretty fierce competition.
Social networking/blogging whatever else fb does, mobile OS, desktop OS , web search, credit cards, online advertising, online videos, web mail, ... Maybe cloud hasn't found the clear winner yet
