I hate to be the detractor here, because getting rid of IE6 would be great for everyone, but do we really expect discontinuing Google Docs and Google Sites to have any effect on IE6 market share? They're mostly corporate users, which means they're probably using MS Office (and have a web team or contractor) anyway.

No, but this makes it just a little bit easier for web developers to convince their boss or client that IE6 isn't worth supporting.
