Just saw this on TUAW and finally made the plunge. I told my wife that I wouldn't buy any navigation software until I could get a quality, name-brand app for under $35. This fits the bill! Plus the add-ons are super cheap--$12.99 for each region? That makes it $50.97 for the U.S. I love how huge my region seems to be in the midwest. Covers everything from Colorado to Ohio. Being a college student, that's my normal range anyway, aside from Florida. Though I won't be going down there until next year so later I can pick up the east coast if I need to. I also love how they overlap the states in each region so that people who would be borderline don't get completely screwed over and can pick which side suits them best.
Good work Navigon! Too bad the app is so huge though. I wish the file size was only 1/3 normal. I also wish I could download over 3g. My cable internet has been sucking again today around 500kbps when I'm paying for 12mbps. AT&T runs between 3 to 5mbps around here. Hopefully my app is installed by morning. I'm excited to play with it!
