Apple, Google, Microsoft and who would be next?

All these companies share something in common:

Microsoft is no 1 in office tools and operation systems and are ubiquitous

Google is no 1 in search, affiliate marketing, mail and web UI

Apple is already no 1 in MP3 players and slowly becoming no 1 in mobile head sets as well as PDA and lap tops. It will take few years and they would become the world leading personal hardware provider (mobile, PDA, MP3, etc...).

Who will become no 4... Well we should wait a few years to see. I think i have a clue... but it is too risky to share it now...
