With little fanfare, Apple began selling the new iPad mini with Retina display on 12 November 2013. Currently, your best bet seems to be to order online and wait 1–10 days for shipping, but Apple is also offering in-store pickup for Wi-Fi models. (One interesting note: while the new iPad mini uses the same A7 processor as the iPhone 5s and iPad Air, it appears to be clocked at 1.27 GHz like the iPhone 5s, instead of the iPad Air’s 1.39 GHz.) follow link
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.
