Finderbar 1.5

"Semi Functional but requires some enhancements" by taxstin on Oct 16, 2011

Pros

Has a great Mac feel
Shortcuts (hotkeys) are nice

Cons

The text (if it's white) looks horrible on non-dark wallpapers.
The ability to right click with your mouse makes many of the functions obsolete.

Summary

It basically boils down to aesthetics. If you use a nice font and appropriate background it can actually look like the real thing. Speaking of which to fix the text problem I mentioned earlier you should edit your non-dark wallpapers by using a photo editing program to add a dark bar to the upper left hand corner where the finderbar will overlay. The text looks much better this way.
Functionally it doesn't do much that you couldn't already do without it, in fact I would say it's an inconvenience to use but it does look good.
