Considering that the sale page says among other things:
"Fine Print – iPad not included with purchase of iSO machine; neither are any necessary embroidery hoops, cables or sewing supplies. Scissors cuts Paper, Paper covers Rock; Rock smashes Scissors which makes them difficult to use when sewing. All orders placed before March 31, 2011 receive free shipping. Any order placed after that date will have some availability problems."
Yes, I think it's an April Fool's joke. But I wouldn't discount either Brother or Singer Sewing Machines do this eventually; there actually is a machine that will interface with a game boy and sew out embroidery patterns!
