A couple comments on the data topic:
Calculating route distances is a bit tricky. You can't simply measure the
distance between two points or turns in a route. You have to take into
account the curvature of the line between the points. I should think all
commercial products do this correctly.
Map data certainly varies so a route using TomTom could be slightly
different than maps using Navteq, now called Here. FYI, Mapquest does not
have their own data. They license it first from Navteq and then more
recently from TomTom.
One challenge in evaluating data is that it varies around the country. It
varies from city to rural areas. It varies between residential streets and
highways. Just because it is bad in your area, does not mean that it is bad
across the country. Map data is similar to wireless phone service. If you
travel, national coverage is important. If you are concerned just with your
home town, then the provider that is best locally is important.
When it comes to POI data, things are even more complicated. TomTom has
their own POIs and they also license premium data from another supplier. Not
all vendors license all levels of POI content. Some map programs focus on
restaurants and travel POIs and disregard services like plumbers or
dentists.
When we can, we do something few if any map programs does, we offer options
so people can pick what works best in their area. This isn't always
practical because of data licenses costs and restrictions.

Good day Sunshine:
I wonder if both GPS systems are calculating in the same way? In
determining the distance between two points, there may be a difference
between traffic and walking.
I believe both Google and Seeing Eye GPS have virtual route features though
I'll have to double check on that one. Seems to me I did use Google maps to
explore an entire route from home.

We were trying to figure out the mileage between my house and The American
Red Cross. The GPS app says 4.1 miles, but with Google, as determined by
paratransit, gives an indication that I am 5.7 miles from The American Red
Cross. That's quite a difference. Here, any trip under 6 miles is $3.00 and
any above, an extra 50 cents. So it looks like the mileage is not accurate.

hello all, I want to weigh in on what mike may said here. you love
foursquare, my point here, please get google maps in the next version of
this app, like we've been asking you to do sense 1.0 and call it a day. do
you know, that we got a bypass here in my location, after the bypass opened,
with in two days of that road opening, google maps starts telling me turn
right on to state highway 9, where your app and some others keep telling me
to continue on to 190. I'm sorry, but for almost real time updated map info
google maps will be your best way to go verses tom tom and map quest.
