Ever since Google updated the web-based Google Talk gadget, I’ve firmly felt that the web-based Google Talk is head and shoulders above the desktop client (if you don’t need file transfer or voice calls, that is). Last week we told you about Prism, Mozilla’s update to the stripped-down browser and web application environment WebRunner. Put the two together (using this URL when you create the Prism application) and you’ve got what feels very much like a desktop version of the Google Talk gadget. Prism is still very early in development, currently Windows-only, and—honestly—requires way more memory than I’d like (around 30MB for my Google Talk), but with more time and development, the single-use approach to web applications as desktop apps could catch on. Thanks Jon!
