I purchased a TomTom One 130 in October and have found it to be invaluable! It helped me in negotiating the weird streets of a huge city and gave me specific directions to wherever I needed to go.
I do a lot of travel in North-Western Ontario, and its directions in cities and larger towns are very specific and direct. I would like to see more attention paid to some rural areas, as the information outside of my city is very vague and non-specific, sometimes not even showing roads.
