Apple is currently the leader in mobile devices, including the various iterations of the iPhone and iPad. However, HP and Motorola are breathing down Apple's neck and may soon be contenders for first place, says analysts.

Prior to the Mobile World Congress, it was expected that Samsung's latest product launches, Galaxy S2 and Galaxy Tab 10.1 would be equipped with a proprietary processor; a successor to the Hummingbird that sits in the Galaxy S, called Orion. It has two processor cores and a clock speed of 1 GHz.

Several sites on the net are now reporting that the nVidia will deliver its 2nd-generation platform to Samsung, the one presently found in the Motorola Atrix. This is apparently because Samsung does not have high enough production capacity for the new processor.

It is likely that Samsung will deliver its Galaxy S2 with different processors in different markets. So far nothing is confirmed by Samsung itself about what kind of equipment that ends up in the final Galaxy S2, or which version ends up in which parts of the world.
