Without the "ThinkPad X6 Tablet UltraBase" expansion dock, the X60 is slightly less functional. It does not have an optical drive built-in, which means no CD or DVD drive. To use CDs or DVD on the go, one must have copied disk images to the hard drive with an included utility, or one must use an external USB CD/DVD drive. There are three USB 2.0 ports, a single 4-pin FireWire port, built-in SD/MMC card slot, dial-up modem port, infrared port, embedded WWAN, VGA video out, audio input and output jacks, and a much-appreciated PC Card slot for flash card readers, USB expansion ports, etc. Essentially, any expansion needs could be managed by way of PC cards or USB devices.
