While the offering is certainly interesting, I couldn't imagine too many people will love to work on documents online.

Just as Microsoft Corp. is about to roll out the latest version of its cash-cow Office applications, Google Inc. is beefing up efforts that could win away some of the customers Microsoft is targeting.

Google's latest move, expected to be announced today, is a plan to bundle its existing word-processing and spreadsheet offerings -- online applications that people can use through their Web browsers -- under the name Google Docs & Spreadsheets and more tightly weave them together. The services, which are available free, offer more-limited functions than Microsoft's word processor and spreadsheet programs, which people use the old-fashioned way on their personal computers.

Google Chief Executive Eric Schmidt told reporters last week that Microsoft's hold on customers who aren't "professional users" of its core Office product "may be vulnerable." The Web search giant is targeting average consumer users and organizations such as universities as it continues to expand email, calendar, spreadsheet and word-processing services that overlap with Microsoft offerings.
