most converter designs have a 1bit converter BEFORE the filter then->Decimation filter-> convert to PCM. The reason you need a filter & decimation filter before the encoding is to conform to PCM. 1bit eliminates the filter & decimation filter need.
1bit could have been used a long time ago, but storage & data bus speeds were a issue for some time, so not much attention was spent on it.

The simple way to explain it is:

PCM adds a filter & decimation filter before and after the encoding(AD & DA).

1bit only adds a analog filter on the decoding just so it does not fry your speaker & amp.

1bit recording has less influence on the sound before and after its recorded
PCM - the AD and DA can very much effect the sound before and after. (similar to how a mic pre or console might affect your sound).

I don't think most of the public will care all that much, but our job is to produce the best quality we can and i know most of you all work your tails off (and spend lots of money too) to get a great end product. Just because iPods are popular, does not mean we have to go get a lobotomy.

If respected audio people don't try, who will?
