I finally upgraded to this unit from my prvious nuvi, which I've owned for 5 years now, and I was very pleasently impressed with this product.  The larger screen and brighter screen was easier to read.  I'm also very grateful that they switched to a QWERTY keyboard, makes entry faster and more accurate.  Oh, and now you can enter a city by zip code, which is also much faster for me.  I also like the traffic notification, very nice.  About the only thing that I don't like is the little advertisement that pops up now and then.  I wish I knew how to shut that off. 

Question: What is display?
Answer: The larger screen and brighter screen was easier to read
