Iphone 4 to start Mobile video convergence

Everybody is very exciting when Apple has recently launched their latest machine, Iphone 4 at WorldWide Developer Conference 2010 (WWDC). The latest Iphone model is being loaded with owesome features like multitasking (capable to open more than one application at one time) and mostly capability to handle video call or video chat. Not only with video call capability ,  the latest model is powered by Retina Display, the 960 X 640 backlit LCD display boasts a pixel density of 326 pixels per inch, making it the highest-resolution phone screen ever. To achieve this, Apple engineers developed pixels so small — a mere 78 micrometers across — that the human eye can’t distinguish individual pixels. That makes text remarkably sharp and graphics incredibly vivid. IPS technology also provides excellent color and contrast from almost any viewing angle.
The most significant outcome is that Apple is focusing attention on the iPhone 4’s video calling capabilities, apparently making “the dream of video calling a reality”. In typical Cupertino fashion, this conveniently overlooks the fact that video calling has been a reality for a long time. The front end camera with 5 Mega-pixel resolution is capable of shooting 720p30 HD video. Video Call can be made from Iphone to Iphone through WIFI, yet still not capable to deal with skype.
Another important improvements is the A4 processor the iPhone 4 now shares with the iPad. While Apple was happy to declare the 1GHz clock speed of the iPad, it has been less forthcoming with the iPhone 4, and it’s very possible the chip has been downclocked somewhat to conserve battery life. Either way, the chip itself is a tighter package that uses less power while running faster than the processor in the 3GS, and that’s always a good thing.
Wait the sec. Just heard that Nokia says about their new N920. The new N920 / RX-57 will have OMAP 4440 processor, which means they have capability to support 1080p30 with HDMI 1.3, yet will eat up battery life (hope they can increase battery also). The processor  versions are dual core SMP enabled ARM Cortex A9 processors on a 45-nm die. Both OMAP processors have dedicated graphics cores to off load the encode/decode of various video codecs and APIs like OpenGL, which (IMHO) makes the OMAP processor the best choice for the computing devices in this category. Are they really real? Are all High Definition (HD) for Iphone 4 and/or N920 just for real? Will you experience the same as what you with get with 32″ HD TV? just with small screen and try to make video call, not only local processing is required, but also compression method to transfer video from one the another. Yet pretty much depending on the Link (WIFI or 3G) reliability
