CoRD is a Cocoa-based app for accessing Remote Desktop. The speed is comparable to MS’s client, but with no bookmarks, keychain integration, etc., file this under “revisit at 1.0″
Right now the biggest reason to use CoRD is if you want to use concurrent multiple Remote Desktop sessions. That’s not possible with MS RD Client unless you make copies of the executable and run each independently. Bleh.
Two wishlist features it may have someday are “Quicksilver plugin” and “VNC Support”, now that would make it a killer app.

And from the Linux realm, we have KRDC. This is what I have historically used for all my RDC and VNC needs. Very useful, and integrated tightly into KDE, if that is your cup of tea.

Hopefully that’s CoRD evolves into that with Quicksilver support.
