It would seem to be counterintuitive to spend a lot of hours getting an alternative "Operating System" on an iPAD but somebody has done it already:
Hexxeh was able to put Chrome OS on an iPad because the open source code for the operating system is available in its Chromium state, but it's not necessarily true that Apple will allow iPads to run other operating systems going forward. That's typically not a level of openness found in the Apple playbook.
Nevertheless, it's worth considering what it might mean to have a robust OS like Apple's on the same tablet as one that runs a cutting-edge operating system like Chrome OS. Why wouldn't users love that? After all, a big part of the iPad's success is its facility with the large ecosystem of apps available in Apple's App Store. But Chrome OS is optimized for using cloud apps of all stripes, and is also said to be a speed demon in early incarnations. Why wouldn't Chrome OS, running alongside another operating system, make for an ideal tablet?
