I don't know--a personal computer, these days--a computer designed to only be used by one person, to only have one account and to be completely personalized to their use--is not a desktop, notebook, or tablet; it's a phone. And the majority of phones run Android. I think we're already there.
Android itself is "open", not "free"; the result is that the users of Android--hardware manufacturers, not the end customer--have the right to restrict the rights of others to modify that software and benefit from its openness, a right which many vendors take advantage of: Android is thereby not an example of "free software" (with the exception of the Linux kernel it bundles, which sadly doesn't provide users much benefit in this specific context as, in addition to supporting opaque binary blobs in drivers, it continues to use GPL2, which failed to protect against the threat of hardware manufactures designing locked bootloaders).
Although, you should notice that the bug specifies "only free software".
It's pretty hard to find an Android phone running only free software.
