For example, Safari for Mac (Leopard 10.5.3 or Tiger 10.4.11) will now be able to access all Gears-enabled sites such as Zoho Office, WordPress, the new YouTube uploader, and Google Docs without Internet access. This is ideal when traveling where you might not necessarily have access to a reliable connection, and helps makes Web-based office apps a more viable alternative to desktop apps.
Not only will you be able to do things like work on your Web-based office documents offline, but Google Gears will also improve browser performance because of the background loading of JavaScript. This was a missing component in bridging the gap between the Mac desktop and the Web. Mac users can expect to enjoy many more desktop-enabled Web applications to come as new services begin to support Google Gears for offline access.
