Touring bikes will be heavier, particularly the wheels, so they will generally be slower to get up to speed and somewhat slower getting up hills. If you aren't loaded, there isn't a huge difference in weight between touring bikes and other bikes, and you can haul pretty well.

Depending on the rims that you're using, you might not be able to use skinny tires. (See http://www.sheldonbrown.com/tire_sizing.html#width.)
