Little noticed amid all the hubbub about Mobile Me, the App Store, iPhone killswitches and everything else, was the news from last week that Chandler 1.0 for OS X was finally released.
If that leaves you only fractionally less in the dark, here's some background: Chandler is a cross-platform, open source Personal Information Manager (PIM), and project of the Open Source Applications Foundation. The vision behind Chandler and the OSAF is that of Mitch Kapoor, designer of the original "killer app" for the PC generation, Lotus 1-2-3.
Chandler has been many years in gestation, but that's hardly surprising when you look at the feature set - there's a huge amount of stuff packed in there. The 3-minute guided tour (direct link to .mov file) is well worth watching for an overview.
The very first thing that catches my eye is the "Quick entry bar", which looks just like the search boxes you see in many other OS X apps like Mail and Safari. This one isn't just for search, though; it's also for rapid input. You type something, hit enter, and it instantly becomes a new item in Chandler for you to edit, expand on, and deal with later.
Chandler is a free download from chandlerproject.org. We'd be interested to hear what you make of it.
