Has anyone else checked out TYPEDNA for font management? It can be used as either a standalone or within Photoshop (I'm using CS5). It's very fast and you can activate and deactivate fonts on the fly. You can also create your own categories for fonts to make your favorites easier to find.

I've been using it for a few weeks and have not come across any negatives so far. Well, except for the price - $49. You can download a fully functional copy and use it for free for 3 months.
