The post-WWDC peanut gallery is atwitter with the idea that Tiger’s Dashboard is a blatant rip-off of Konfabulator. You can’t read anything about Dashboard without hearing that it’s a Konfabulator rip-off.
Bullshit. Dashboard is not a rip-off of Konfabulator. Yes, they are doing very much the same thing. But what it is that they’re doing was not an original idea to Konfabulator. The scope of a “widget” is very much the modern-day equivalent of a desk accessory.
