NVIDIA CEO Jen-Hsun Huang revealed in an interview with Fortune that the Tegra 2 SoC will get in just about any tablet but not the ultra expensive device from Apple:
He said some things that we do know, for example that Tegra one is shipping in systems and that Tegra 2 chip is developed but someone has yet to announce a system based on it.
Since Jensen underlines that Tegra 2 can run great even with HD1080 video, can do great flash and still have multitasking and great battery life, Nvidia clearly believes that its Tegra 2 is better than ARM based Apple rebranded A4 chip. We know that this is coming and have mentioned it here and here.
When asked if Tegra 2 will get in the iPad, Jensen replied that it won't but he added that Tegra 2 will get to just about anyone else's tablet but not the ultra expensive device from Apple.
