ARTOORO  Viscosity is better than any openvpn client you'll find for any platform. Windows, Linux, and Mac OS X.

I absolutely love Viscosity and use it every day. For the price you can't go wrong.

Viscosity makes OpenVPN fun to use (especially if you've used other clients in the past)

ARTOORO  I've been using Cyberduck for a couple of years, I really like the feature set, and the the bookmarks are really cool. In my opinion it's the best free open source FTP client available on the Mac.

But I switched to Fetch 5.2 last week due to stability. Fetch doesn't crash on me all the time. I hope Cyberduck gets better is this regard, but until then I'm using Fetch.

ARTOORO  OpenOffice is the best cross-platform office suite available. I would use Pages but it lacks good formula features and is not cross platform.

I use OpenOffice Calc for business but when it comes to word processing or presentations, iWork is a much better choice unless you require OpenDocument compatibility.
