I just put Golden Eagle software on my laptop about 2 weeks ago, and I've been using it on the road pretty regularly - it's pretty good, way better than the old Cirrus. It's got a few little bugs and quirks, but it's the "1.0" version so I hope that stuff will be fixed.
I think I'll try FLTPLAN.com too - it looks sweet.
BUT the chief advantage with Golden Eagle is that it doesn't need an internet connection to get data - you can use the DUATS 800 number which means that you can use it when your internet is down (a nice backup), or when you are in a podunk FBO or hotel room. Plus it gives you "official" DUATS weather. I give it 2 thumbs up, overall.
