DEVONthink Pro Beta 2
DownloadSquad points to the recent update of DEVONthink Pro Beta: "This second beta introduces a number of enhancements such as more applescript support, an optimized widget, new scripts and online help."
If you're a Spotlight aficionado, then you probably won't find much use for DEVONthink. I, however, don't like Spotlight much, and love using and recommending DEVONthink Personal Edition. I've collected a rather large gathering of webpages, PDFs, images, and text files in my fully-searchable DEVONthink database, and it doesn't return results I wasn't looking for, like cryptic System files that I never touch. The public beta is free, so go grab a copy and give it a whirl. Make sure you check out the Services included as they really make importing info into the database easy.
