Some might be thinking this should be in the iPad section, but I am putting it in the iphone because my idea is presented to suggest that the same A4 chip will be launched on the 4th gen iphone. So does anyone know what the A4 stands for? A for apple presumably.. but why the 4? I did a quick search and couldn't find anything. I believe it to mean that this chip was designed specifically for the iPhone OS 4.0. This would suggest that the same A4 chip will be put in the newest iphone and ipod touch. Which is quite exciting. Imagine the power consumption improvements! If you want to take the name "A4" a step further I believe it might even stand for Apple OS 4.0; a shift from iPhone OS 4.0. This transition seems quite logical to me. I mean the same OS runs on three different devices. I think it's only a matter of time till the name changes from iphone to something more generic... and as apple is continuing it's focus into the touch domain (iphone, ipod, ipad, eventual iMac that's rumored??) I think it's likely that the primary OS will eventually be based around this touch "iPhone" OS. So it makes sense to call it Apple OS and continue to expand it and grow it until it is at least equal in computing power to Mac OS. Possibly eventually even taking over as the primary (or only) OS made by apple. Just some thoughts.
