I've been doing some reading of a few different forums regarding dashboard, and it's interesting to read some of the thoughts. I have some of my own.
#1. The whole concept of the widgets are not new. yes they have been implemented by a third party developer but that happens all the time. who really complained when apple released safari?
#2. While konfabulator has some cool features, it will not convince anyone to buy a mac when they are using it at an apple store.
#3. Apple probably wanted certain widgets to be in the system. Does anyone expect them to release those widgets under konfabulator?
#4. I think this will be something that becomes an essential part of the OS. However, the tie in to Expose is what will make it so important to me. I can't even count how many times i've wanted something like this, and I have not been happy with what's out there already. Apparently Apple felt the same way.
The fact of the matter is that the goal of a computer company is to sell computers. Relying on another company to deliver something like this is silly. By including it with the OS you're increasing the value of the computer. I will be quite happy to see this included.
