If you’ve been pondering the purchase of an iPad mini, Dan Frakes’s detailed review at Macworld should give you the details you need to make an informed decision. Overall, he’s extremely positive about the new iPad, giving its form factor and non-Retina display high marks, but acknowledges that it doesn’t make sense as an upgrade for people who don’t think they could go back from Retina display-equipped devices or for those who need the larger screen and higher resolution of the standard iPad for serious work. follow link
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
