The Objective-C model of object-oriented programming is based on message passing to object instances.
Sending the message 'method' to the object pointed to by 'obj' requires following code: [obj method:argument]; Information Architecture Interaction Design Visual Design Smartphones and Personal Computers What Critics Are Saying Calender

Over-the-top communication “One of the most interesting facts that was pointed out was how a third of Nvidia’s revenue now comes from selling chips that aren’t for traditional PCs. In the last year, the number of tablets shipped using Nvidia chips, like the Tegra 3, have doubled. “ “Traditional computers are far from dead. PC and server CPUs are estimated to pull in a combined $41 billion in 2012. In comparison, mobile chips will likely in the $5 billion range. It’s quite clear that mobile devices are growing at an incredible pace, so the once dominant PC market is taking the back seat.” Why is the PC staying strong despite increased use of Smartphones?

-Proprietary, cross-platform instant messaging app.
- What can you send?
- Text messaging
- audio media messages.
- BlackBerry OS
- Series 40
- Symbian (S60)
