I recently got Microsoft's Streets & Trips & loaded it on a laptop . The laptop has a 17" screen which is easier to see--- but ---I am having a bit of a time getting it situated correctly. I bought a laptop stand but it still is about 6-8 inches too low . I can see the screen ok but it is not yet quite right.
Alpine wanted $ 1700 for me to upgrade ..... My system is probably 10 years old and the most current map info is 2005. The Maps & Trips software was $ 79 and it is pretty good -- so far. I got the GPS module with it and it seems to work fairly well.
I just need to figure out how to get the laptop positioned right & then I will be in good shape........ I will keep working on it.
