They go by a variety of names (you'll find 'carving toys' and 'Big Feet' in there too!).
Generally these new gadgets are 80 - 90cm long (less than half as long as traditional skis) and you can choose to use ski poles or not. They are great on groomed runs, in snow adventure parks, in moguls, on steeps and up to 6 inches of powder.
Because of their limited floating surface they start to nose-dive or submarine with a lot of powder! Riding them is a blend of in line skating and downhill skiing.
