I doubt there's enough of a market for the use case alone, but nice Chromebooks are perfect for travelling internationally - you can reset them before border crossings and quickly restore them after passing through border crossings where anybody is liable to ask for access to your devices.
ChromeOS can run desktop Linux software and Android software, so it definitely isnt worse than Mac. Its probably even better than Windows. Of course, if you need Mac/Windows software, Web/Android/Linux alternatives might not exist or might be worse. But the devices are hardly lacking software compatibility.
For reference:
> Cameras aren't yet supported.
> Android devices are supported over USB, but other devices aren't yet supported.
> Android Emulators aren't yet supported.
> Hardware acceleration isn't yet supported, including GPU and video decode.
> ChromeVox is supported for the default Terminal app, but not yet for other Linux apps.
