Windows only: For some time now, Google Talk has been more appealing as a web app than in its rarely updated desktop version. That changes, somewhat, with the release of Google Talk Labs Edition for Windows. The desktop client, which looks a lot like its web counterpart, includes the same group chat, emoticons and tabbed talking as the web, and puts pop-up notifications for Google Calendar, Gmail and Orkut events in the corner of your screen—which is a nice, consolidated way of getting that Outlook-like functionality. The big trade-off, however, is the lack of voice calling or file transfer through the Labs Edition, so if those are regular features, you’ll likely want to stick with whatever version you’re using now. Google Talk Labs Edition is a free download for Windows systems only.
