It is the goal of OKPC, to provide all the kids that have an XO-laptop, with a tool they can use to actually create things.

• XDs work equally well with wool and cotton yarn
• All movable parts (like needles) can easily be replaced, even by children
• The XD requires no external power source. Everytime the knitting carriage is moved along , the built-in battery for the pattern controller is recharged to run for another minute.
• The XD can be used as desktop-machine (like normal home knitting machines) or as laptop-machine, since laps can be found everywhere, whereas desks may not.
• Two XDs can be plugged together, to form a double-bed knitting machine.
• The XD has a standard USB port - contemporary home knitting machines require expensive and proprietary cables to connect them to a computer - all the XD needs is a USB-cable.
• The XD hardware is open, and modular. The kids are free to open their XD, rewire the hardware, and create circuit-bent pullovers whenever they like.
• The XD pattern protocol is open. Open Source Projects and XO-Activities to control the XD will be freely available.
