While this is a much discussed subject of debate, my $.02 is that a higher bottom bracket only matters on the track. Two of my previous fixies have been converted road frames with low bottom brackets, and my current bike is a Steamroller. In the three years I've been riding fixed, I've never had an issue with pedal strike.
Additionally, I've never struck a pedal on my Surly Pacer with 180mm cranks and the same BB drop. While I realize that coasting makes a difference, I've also aggressively raced the bike in criteriums where I've pedaled hard through corners.
For commuting and bopping around town, you won't get anywhere near the amount of lean required to strike a pedal on the ground.
