At what point in time did the universe inflate to a size larger than the observable universe?

Wikipedia cites Alan Guth saying that (in 1997) the universe was currently 10^23 times bigger than the observable universe. Is this correct? Additionally, if the universe started as small as it was and inflated so far past our observable bubble, but still is some number of times bigger than our observable bubble, how can people say that it is infinite?

The universe doesn't have a size. It just keeps going and going.

You should probably bear in mind that a *lot* of theoretical cosmology has changed radically in the past decade or so, due to new observations. Anything related to cosmology that dates from last century has a better-than-even chance of being wrong.
