How can it be out of beta when there is still no Mac or Linux version? Will those versions spend any time in a beta state?

If the Mac and Linux versions are initially released as beta, it seems odd to me to have one product in differing states of 'completeness' on different platforms.

However, I can't imagine that Google would give the Mac or Linux versions the gold star seal of approval right off the bat.

Does anyone know about the status of the non-Windows versions of Chrome? It'd really be nice to use it, but I use a MacBook Pro at work and Ubuntu on my dsktop at home.
