Hmmmm... Pretty much every aspect of board manufacture has changed in the past ten years. Resins are more durable, core materials and profiling are better engineered. Topsheets are thinner, lighter, and more durable. Edges are stronger, hold a longer-lasting edge, and are now often profiled for better edge hold in carved turns. Sidewalls are now engineered for dampening and improved edge hold. Basalt, Kevlar, carbon fiber, and bamboo inserts help to get more/better edge hold, power transfer, turn initiation, and pop. Camber profiles like RC, C2, Camrock, etc really do maintain hardpack carving ability while drastically improving float. Wax-infusion and molecular engineering of sintered base materials yields faster, more durable base materials. Progressive side cuts yield better turn initiation and cleaner carves.
Snowboards are now lighter, just as durable, better performing, and many are much more able to handle a variety of riding styles and snow conditions.
