The most reliable Windows laptop is… the mid-2012 13-inch MacBook Pro running Boot Camp, according to a report by PC management firm Soluto. Over the course of a three-month study, the MacBook Pro bested models from Acer, Dell, and others thanks to its superior construction and lack of the commonly preinstalled Windows “crapware” (to quote the report). It is the second most expensive machine in the top 10, cheaper only than the 15" MacBook Pro with Retina display that ranked 6th in reliability. 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.
