Apple's 15" Portrait Display is the last of the company's original line of external Macintosh monitors, first introduced in 1987, to be removed from the product family. The vertically oriented greyscale display (Apple item M0404) is still available until existing supplies run out, but no more will be built. [MHA]
Disable Caps Lock
If you find yourself pressing the Caps Lock key accidentally as much as I do, note that you can disable it entirely in Mac OS X. Open the Keyboard & Mouse preference pane, click the Modifier Keys button, and in the dialog that appears, select No Action from the Caps Lock pop-up menu. You could remap it to another modifier instead, but that might make using differently configured Macs more difficult.
