Regarding the Apple “copying Konfabulator” controversy:
The idea of desktop widgets that pop up on the screen when you press a key is far from new. In 1984, Borland launched Sidekick 1.0 for MS-DOS. When you pressed a magic keystroke, a calculator, notepad and calendar would appear overlaid on your screen. Push the key again, and they vanished.
Also in 1984, Apple’s original Macintosh operating system had Desk Accessories, small tools which weren’t full applications, but which could be launched on top of your application windows.
This is the way the software industry has always been—you have to keep innovating, or someone else will do what you’ve done, and do it better. If the Konfabulator guys want to innovate and compete and try to jump ahead of Apple again, I have some ideas I’d be happy to share with them for free if they contact me. (I’d much rather pay them $25 than write and support the code myself.)
