I can understand that, but calling them 'bad' right off the bat is not necessarily true. Let's use a digital watch as an example. Digital watches are designed to be small enough to fit on your wrist. As a consequence, there are physical constraints on the number of buttons you can put on the side whilst maintaining usability. If you allow the use of a modal user interface, you can use fewer buttons. The downside is you have to read the manual to configure your watch. My point may be moot, though; who uses a watch in the 21st century? I use my phone to tell the time.
