A number of readers (some from the audience at Web 2.0 Expo) wrote to let us know that Google is adding presentations to their Docs and Spreadsheets package. With the announcement the company revealed that they have purchased Tonic Systems to help with the new presentation software. It's expected to be ready by summer. Google's CEO Eric Schmidt was asked if Docs and Spreadsheets will compete with MS Office, and he said, "We don't think so. It doesn't have all the functionality, nor is it intended to have the functionality of products like Microsoft Office."
