Ah, ok, but it doesn't mean that Dashboard was ever in their plans. They probably saw the potential of having widgets when they took a look at Konfabulator. Heck, there were probably people at Apple who used Konfabulator.
Whether Dashboard is better than Konfabulator is also a bit irrelevent. It doesn't mean Apple didn't decide to go ahead with something like Dashboard because of Konfabulator. I'm not saying that Apple only started Dashboard because of Konfabulator, but I'm just saying that there is this possibility and people dismiss it without even wondering if they did. For most people, either Apple came up with it first in the 1980s, or Dashboard is a ripoff of Konfabulator. Why not a bit of both?
All this talk about what happened in the 1980s seems irrelevent to me. The point is that if Konfabulator never existed, Apple may have never added Dashboard to OSX, whether the groundwork was there or not, or whether Apple did implement something like this in the '80s.
