The Latitude D520 looks a lot like the other new Latitude notebooks in design.  It may seem quite similar to the D820 and D620, and in some respects it is because if offers the same sturdy magnesium alloy build.   You can configure up to a 2GHz Core 2 Duo processor and up to 4.0GB of RAM.  If you are looking for something with a more square aspect ratio for graphics and do not like widescreen displays, then the D520 might actually be quite appealing for you.
