I can fill my small post with rumors but you will get nothing at end, the important I think are features that were expected in the iPad 2 and iPhone 4 previously, but are rumored for iPhone 5 and iPad 3 again:
iPad 2 and iPad 3:
Camera: All of us expected a camera with a flash for iPad 2, but that never came. iPad 3 is on its way and is rumored to be equipped with one.
Processor: The iPad 2 flashed a 900MHz dual-core ARM Cortex-A9 processor, Apple A5 chipset and PowerVr SGX543MP2 GPU. That made the tablet one of the main contenders in the tablet market war. Now the iPad 3 is about to be introduced to millions of customers and is rumored to sport a Quad-Core Processor, most probably the A6. That will make the tablet as powerful as any high-end desktop computer.
Operating System: iPad 3 may see a major change when the OS of the most awaited tablet is discussed. The iPad 2 was powered by iOS 4, and now, as rumored, will the new iPad 3 see the next-generation iOS 5? Rumors regarding the OS go even deeper as the tablet is also expected to run OS X. If a quad-core processor, as mentioned earlier, is really coming then there are high chances that Apple may also introduce OS X Lion for the tablet.
HDMI: Previously, Apple introduced the HDMI playback in iPad 2. This, however, had problems of its own. The user needed an additional digital AV adapter which is available for $39. The upcoming iPad 3 is expected to end the problems regarding the additional HDMI cable with an evolved HDMI port.
New Retina display: The retina display was expected in iPad 2 but Apple decided to carry on with the display of the first iPad. Now the iPad 3 is being heavily rumored to arrive with the retina display. An improvised resolution of 2058X1536 pixels is also expected.
Note: The rumors also claims that the third-generation iPad will be “even thinner and lighterâ€, with high-resolution increasing to 250dpi.
iPhone 4 and iPhone 5:
It is the hard part, talking about iPhone {4 or 5], features that were expected in the iPhone 4 but are rumored for iPhone 5. Honestly it make me angry man because I can’t afford another failed version from Apple, I wonder why Apple doesn’t read and work to make the perfect one we expect.
For example Designer Michal Bonikowski feels that the new version will be safe and predictable. In his conceptual version he converts glass enclosure into proven aluminum; steel frame remains as a reference to the previous version and directly to the iPad 2. Also, the key functions is converted from mechanical to sensory.
Another example from Antoine Brieux, who designed what you can called a natural evolution, apart from making the next generation iPhone a piece of pure glass.
At last we have wait and post, you have to wait and read, but you can leave your comment, may be Apple read … Who knows !!!!!!!!!!
