OMG! OMG! From the Advanced Technology section of Apple's Tiger Preview:

Remappable Modifier Keys


Remap modifiers such as control and caps lock to be super elite.

Who knew that remapping modifier keys required Advanced Technology?

Now I've got to upgrade! I mean, uControl is nice and all, and it's made life under OS X bearable, but it's a bit on the flaky side. The caps-lock LED continues to turn on and off even when caps-lock is changed to another key. Also, caps-lock-clicking on links in Safari does different things depending on the state of the button, despite the fact that it's now supposed to be stateless.

Please, oh please, Apple, don't screw this up! Give us a way to remap modifier keys arbitrarily, not just a “swap caps-lock and control” checkbox. In OS X it's handier to have caps-lock be command, since that's the main modifier key for most keyboard shortcuts.

On a more serious note, it's nice to see that the basic unix command line utilities like mv, cp, and tar will actually finally work reliably in Tiger. Up until now, moving a file using mv would cause its resource fork to be lost, potentially ruining it. Pretty shameful for an OS claiming to be “Based on UNIX“.
