Dry laid pavers and brick

Does anyone have experience with installing a dry laid brick or pacer patio walkway or driveway? Ive noticed it a few places lately and am considering it as an option for a new driveway and or walkway near the house. Anytime i see brick laid with mortar on the ground it has cracked and pulled away frim the mortar and looks like crap. My other option is concrete which also seems to look pretty bad soon after it is installed. I figure at least with dry laid, if there is a problem you can pull out a few bricks and repair it.
