One of the more impressive things that we noticed about the 2100 was that it harbored so many I/O ports yet managing to keep its little dimensions at the same time. We have seen a few of the competitors that lack a PS2 port, or a USB or more likely on-board LAN and/or an onboard modem. The way DELL managed to squeeze all of these into one tasty sandwich is very impressive. It's literally bursting at the seams with ports....

On the back, the 2100 sports the RJ-11 and RJ-45 ports, a Parallel 25-hole connector for Printers and scanners, the external VGA out 15 hole connector, a PS/2 (keyboard/mouse) 6 hole mini-din connector, a minute Power in port and the IDE connector for the external media bay. This can be used for the Floppy drive, CD-ROM Drive, DVD-ROM Drive, CDRW Drive, 2nd 20GB Hard Drive or a ZIP 100 drive.

The underside harbors the 140-pin expansion connector for the Latitude L400 Advance Port Replicator, should you feel the need to purchase one.

The left side sports the two sound ports, one mic in and one headphone jack. Best of all is the single USB port allowing you to connect any USB compliant device.

The right side is the only side left rather fruitless. Other than a single PCMCIA card slot and the Kensington lock, that's your lot. Altogether, the amount of ports DELL managed to squeeze in is impressive.
