Copernic Desktop Search

It may have been coincidence, but the day before Google Desktop Search was released, a new version of Copernic Desktop Search was rolled out. Version 1.1 includes new usability enhancements, more flexible indexing, and greater file compatibility.  Cnet.com gives Copernic Desktop Search the nod over X1. After updating my PC to 1.1, I can definitely see improvements, but I'm still torn. You can't touch X1 for support of multiple file formats. On the other hand, Copernic really does seem less intrusive when indexing.
