Adobe Flex 3 and AIR 1.0 certainly have generated quite a buzz in the Java world in the last few months. Not in the least by the very nice Parleys.com site which is hosting all the Javapolis talks and videos.
Adobe AIR is a technology which lets you download and run webapps seamlessly on your desktop. (similar to Google Gears).
Another well known Google app, Google Analytics has now been ported to AIR by Nicolas Lierman. Analytics features all sorts of interesting statistics about your site visitors, allowing you to make informed choices on how to improve your site (eg. which pages are popular, which are not, which pages have high exit points, …)
The AIR version (with really nice Flex chart animations), can be download at AboutNico
