One nice feature Gnome has that I didn't know of it is Typing Break, found in System -> Preferences -> Keyboard.

It basically forces you to take a break after a period of time. Gets useful after you start getting some hand-aches. During the break you see something like this:

It takes a bit of discipline to actually respect the breaks (especially when something is urgent and you have the "Postpone" button -- which should be renamed to Snooze). Then again, even if I disable the postpone button I might be tempted to Ctrl+Alt+Backspace or Ctrl+Alt+F1, login then kill process.
I'm also looking at some exotic and ergo- keyboards lately. Anyone has something to recommend ?
I would really like something like 2 half-keyboards. One for each hand, then going into the USB port. This way I can place them to the right and left side of the laptop and use them quite nicely -- it's almost impossible to use an external keyboard with a laptop without also adding an external display.
OK, no flying cars. But 2007 and no mind-reading input devices ? Someone is slacking off...
