I switched from my old Buzzword account to the new Acrobat.com account today.

Acrobat.com

The move added a couple of new web services including 5GB of file storage (Share), limited (5 files) PDF conversion, and limited web conferencing (ConnectNow). Bringing up Buzzword and Share seemed much much slower than using Google Docs or Zoho. Share does not allow many media file types (presumably to prevent it being used to share rights managed media). Buzzword is a very very nice web based word processor, however. So, I'll probably take a closer look at it as part of this new Adobe web eco-system.
