My experience of Boston has been completely opposite of yours so far. I have worked in Boston the past 10 years and have been shooting a lot the past two years, people are hot and cold about being photographed but for the most part I have been pleased with responses to my requests. As far as not being scenic, I have had a great time walking from Charles St, to Beacon Hill, to The North End to Newbury St. Come back to Boston some day and we will make a day of it. I just did that in New York City for the day last Saturday......same thing as Boston only WOW, lots happening.
As for the X100, I am trying to find a great compact for low light and image quality. That new X10 is more my budget though.
Some of these are from a rainy day on Charles St in April and others from Newbury St in October.
Your gonna miss 100% of the shots you never take, so keep shooting
