I am disappointed a bit at Mr.Cook's recommendations. I think that some of the major problems with Apple Maps exists outside the United States. I am in Canada, and there was a problem from the get go with maps (well documented, I won't go into it).
None of the solutions recommended in this letter are good solutions. Loading a webpage adds how many different steps to getting an address, Bing and Mapquest are not available in the Canadian store, and Waze looks like a cheap gimmick to me(first impressions, it may be a good product).
I don't want to jump on the 'look at Apple falling' bandwagon, but this is a major blow to their reputation. I can appreciate the letter, but don't offer recommendations in your apology that don't work, that makes you look actually incompetent.
