I agree that some (too much) feature creep is market driven and mostly unnecessary. However, we consumers have to step up and bear part of the blame. When I read user reviews here and on other websites, I often see (or write) the phrase, "This would be the perfect whatsis if it only had..." Unfortunately, we are blessed with manufacturers who actually listen to their market. As a result, we end up with an ounce here and two ounces there as Henry Shires adds a zipper to the Rainbow vestibule, or Granite Gear adds an inside hydration sleeve to the Vapor Trail, or someone adds a functional windscreen to a canister stove and calls it Jetboil.
