I think everyone prefer iterative development. I love web dev because I can get instant gratifications (no compile time). I think it's mostly because I'm lazy though. I also manage a legacy system where I make hot fixes in production, where setting up a testing environment is not practical. While I do introduce bugs, they are far less because I'm forced to plan carefully, and know how everything works. One problem with development is that it's hard to predict what will happen, and thus it gets difficult to make estimates. But if you carefully analyze and plan, things will go much smoother.
