Well they've gone and done it. Google has finally enabled offline access to Google Docs using their Google Gears plug-in. A little late considering Zoho did the same for Zoho Writer way back in November 2007 -- also using Google Gears.
Google Docs and Zoho have always been rather handy for people on the go you can access your documents from anywhere you can get online, you arent having to email yourself documents and its dead handy for teamwork, with users finding very useful the potential for sharing and collaboration that applications such as these provide.
