RouteBuddy review
I've been using RouteBuddy for over a year, since some really rough early releases. The new version 2.0 is a massive improvement over the previous release, bit in my opinion is still not quite ready for primetime. It is nice, but I'd consult a second trusted source for any crucial navigation.
It has fairly beefy hardware requirements. While my Mac is admittedly getting a little long in the face (iBook G4 1.33GHz, 1GB RAM), RouteBuddy is easily the slowest program I have ever run on it. They recommend at least 2GB of RAM, and I'd recommend a newer Intel processor. It is almost just as slow on my Dual G5 with 2GB memory.
The latest version seems to have the "design" of the program down, and it is stable, but there are some serious issues with routing. I've filed some very detailed bug reports with them, and I expect they will have the bugs worked out soon. Over the year or so I've been using (beta testing?) RouteBuddy, they have had many updates with each update making significant improvements. The developers and staff of the company are extremely responsive to their user community (read up on their forums), and are truly dedicated to making RouteBuddy the best navigation/mapping product for the Mac platform. With their commitment to excellence, and ability to think outside the box, I predict that within the next year RouteBuddy will be an excellent option for Mac users that have sufficient hardware.
