Circle of latitude the Earth onto a plane. On an equirectangular projection, centered on the equator, the circles of latitude are horizontal, parallel, and equally spaced. On other cylindrical and pseudocylindrical projections, the circles of latitude are horizontal and parallel, but may be spaced unevenly to give the map useful characteristics. For instance, on a Mercator projection the circles of latitude are more widely spaced near the poles to preserve local scales and shapes, while on a Gall–Peters projection the circles of latitude are spaced more closely near the poles so that comparisons of area will be accurate. On most non-cylindrical and non-pseudocylindrical
Latitude ON Latitude ON Latitude ON is an instant-on computer system made by Dell. It is a combination of software and hardware developed by Dell and used in some of their Latitude laptops. The system is based on a dedicated ARM processor (Texas Instruments OMAP 3430) that runs a custom version of a Linux OS. It was announced on August 12, 2008 along with other laptops, including a potential competitor to the Asus Eee PC and arrived a year later on 28 September 2009. Latitude ON runs MontaVista Linux on an ARM-based subprocessor. This so-called MontaVista Montabello Mobile Internet Device Solution provides
