Arista 730E from Barista.  Pretty cool:

The 730E has a big bright color touchscreen on it that provides on-screen help and graphic tutorials, all powered by Windows. The system does even more than just sewing – it also can quilt and do embroidery. It’s packed with a stitch library with over 850 stitches, over 100 embroidery designs and an assortment of other features I most likely wouldn’t even be able to make sense of because in the end I’d probably be hopeless, despite all the on-screen help.

It also can link to your Windows-operated computer through a USB connection, and has a proprietary memory card.

Downside: It costs $8,199.
