I have tested RouteBuddy for several weeks, trying to use the software to plan my holiday. In short:

The software works, and is OK on the route (version 1.2 allows address search, although it is poorly implemented), and the fact that it automatically connected to my BlueTooth GPS (the basic BlueTooth connection had been established through the Mac OS X BlueTooth Control Panel), was really neat.

BUT... it's damn slow on a PBG4, zooming is extremely slow when you zoom to near-max, it takes a lot of space and occasionally it crashes.

On the plus-side, it allows nice GPS integration with Google Earth / Google Maps.

When at home I use it for giving me a GPS position for Google Earth/Maps, not for route planning, as getting the data from Google Earth/Maps mostly is faster than waiting for the program to render the data.

When "on the move", it's nice to see where I am. And that works quite well. Basically, it's more a "position on a map" program me than a navigation program. Version 1.2 contains basic routeplanning (and with a bit of playing around I can even add addresses found in the address search...if I've turned them into way points first)...but if I have planned a route, it is confusing that the route does not adapt when I drive "wrong".

It works, and it is probably the best option which you can buy for Mac OS X today (assuming that Route 66 is no longer available - I cannot find the software)....but there's still a long way to Prime Time, and I would personally not buy loose BlueTooth GPS just to work with RouteBuddy.
