Dell Latitude

Dell Computer's Latitude laptop brand is specifically targeted at the commercial market (as opposed to the Dell Inspiron aimed at the consumer market). The laptops have a similar design and parts as some Inspiron models. Current models include the X1, D410, D420, D820, D610 and the D520. Select models based on the Intel Core Duo and Core Solo are now available. The D420, D620, and D820 feature Wide Aspect LCD screens: 12.1", 14.1", and 15.4" respectively. All of the Dx20 line will also feature Intel Core Duo or Core Solo processors. The Latitude D620 weighs in at 4.7 pounds, and includes a 1.67GHz Intel Core Duo T2300 processor (667MHz front-side-bus) and 2M of L2 cache. It comes with 512M of RAM, expandable to 4G, and four USB ports. For graphics, it offers the Intel Graphics Media Accelerator 950, and an option to upgrade to NVIDIA discrete graphics at the expense of lower battery life.

System Configuration

Hard Drive: Range from 40 GB to 120 GB hard drives.
Ports: Features a wide range of ports including: two to four (Only for D620 and D820) USB 2.0 (including one via D/bay connector); IEEE 1394; VGA; Fast (10/100) or Gigabit (10/100/1000) Ethernet via RJ-45 port; modem; Audio; SDI/O, CF

The Latitude C-series notebooks covered the range of processors from the Pentium 166 MHz to the Pentium 3-M. Models in this series included the CP (Pentium processors), CPi (Pentium II processors), CPx, C600 and C800 (Mobile Pentium III processors), CPt, C500 and C510 (Celeron processors), C400, C610 and C810 (Pentium 3-M processors) and C640 and C840 (Mobile Pentium 4 processors).

C series laptops were notable for their consistent and interchangeable accessories across this wide range of processors. The series was one of the first to offer the UXGA 1600x1200 resolution display and included a NVidia GeForce MX400 32 MiB Video Accelerator to complement the display requirements. A robust design made it a favorite in harsher climates; however, this design lacked the visual appeal of many of its competitors. The most popular of the C-series included the C800, C810, C840, and later the C640.

An interesting note on the C840 is that it contained a Pentium 4 Processor and utilised Rambus-DRAM instead of the standard SDRAM modules, giving a performance boost to an aging model.

Improvements over the "Dx00" series (ie. D600, D800, etc.)

Two extra USB ports on the side, next to the module bay.
Stronger, more durable tri-metal chassis
D-dock is actually a USB device, and only has drivers for Windows beginning with Windows 2000 and currently XP.
