I just saw the article at http://tech.fortune.cnn.com/2010/12/20/videogamings-online-explosion/ also says that online gaming applications are spreading (similar to my post about ‘Computer Application Trend 2011′). The growing of this business may give only small contribution to the old-style-proprietary platform such as: Nintendo, Microsoft, or Sony, as they are not using those platforms. I believe this makes a new opportunity for this new expertise: server farm and cloud.
Moving further, I also see that thin clients will be used more. Mobile platforms (mobile phone handsets) and their operating systems will also be seen more in the market. So, client platforms such as iOS, Android, Chrome, and others (like Symbian and Bada), may be the way of the future for operating systems.
Don’t bother the big players, but see this as a good opportunity to grow. The market is growing fast.
