Why do you think the author says iPhone 4S uses a Tegra 2? He doesn't say that.
I'm curious, though, is it really a fully open source computer? How does that work when it uses an ARM chip? Or does the open source part refer only to the OS? As soon as ARM replaces ARM11 with Cortex A7 or whatever, we should ask them to open source ARM11.
I'd say its more closed source than open. The schematic is not released, the chip is a Broadcom ARM (not even for sale to the public), the GPU runs a binary closed blob. Even the boot sequence involves closed source binary "magic".
It runs linux. That's open. The rest, not so much. Its still awesome. It just is what it is.

The ARM chip is not open source, and probably won't be at release either.
