Another piece of Google's fabled web-based office suite falls into place with the big G's acquisition of Writely, the web-based word processor that we (and everyone else) have been keeping an eye on since its beta launch last year. To refresh your memory, Writely is the flagship product of Upstartle and lets people collaboratively write and edit documents in their web browser. Writely shares its category with heavy hitter 37signals' Writeboard, Zoho Writer, and many more that seem to be popping up weekly. As Om Malik points out, Google has Gmail and its upcoming CL2 calendar app poised to replace Outlook and Google Base has the potential to replace the likes of Access, so all that's missing for a complete Voltron office suite is a spreadsheet app and a PowerPoint-killer.
