Just the thing to keep an unobtrusive eye on what time it is.
I use one-a-them fancy fullscreen, no-distractions text editors, and so I don't see the system tray. I run clockVetica on the iPhone in its dock next to the monitor, and that provides a nice, low-key way to still know what time it is. Without opening the window on the howling vortex of twitter feeds, status updates, and inbox badges. Yes, you could also put a clock on the wall. But not for ninety-nine cents :)
