Version 4 has been long awaited and there are some great features. I've been using Path Finder for almost two years and haven't seen the Finder in sooo long! The tabs and instant directory updating of version 4 make the upgrade very attractive. The new enhanced find and select features are great as well.

Even so, this initial release has its share of bugs to remove. For one, I find it to be much less stable. The past several days have been good though (crossin' the fingers!). Second, the left drawer just doesn't want to stay open. There are a few other oddities, but none should prevent one from using PF4.
