Three days ago, I bought my first Mac, a MacBook. I've been a PC guy for about 13 years up until this point. Anyway, one of the most useful pieces of software I had on my PC laptop was Microsoft Streets and Trips, which would work with my USB GPS reciever. Is there any comparable software for OSX? It doesn't have to be too fancy, just a program that'll draw maps, give directions, and put a marker at my location via GPS.
