Query: Support Good Software for Mac OS X

Route 66 is not the best software of it's kind but it is the best for Mac OS X. Prior to this I used DeLorme Street Atlas USA which was a better product but not updated for OS X.Route 66 has a confusing interface and forces you to do trip routing their way instead of doing it your way. However once you learn their way the software becomes quite usable. The routing interface needs work.The aquafied buttons, while very pretty, aren't very intuitive.The Appearance and quality of the maps are excellent.The speed of the program while not optimal, is usable(15" PB 1.5Ghz, 1GB RAM).I have high hopes for this software. Hopefully the developer will realize that the Mac market is starving for this kind of thing and Apple's notebook sales are going to continue to create more demand.
