It doesn't even look like a skateboard. I think the reason Boosted Boards looks so awesome is the fact it actually looks like a longboard... with a motor!
It's not even just that it looks like longboard, it is an actual longboard that's been modified. It's a Loaded Vanguard from what I can tell which is a really nice board. The existing electric boards tend to be made specifically for the electric board and the result is a not very good skateboard/longboard.
Also, the difference in weight is huge. 40 lbs is something that I need two hands to pick up and is a pain to carry. Bringing the weight down to just +4 lbs over the original longboard means this is something I can actually carry under my arm.
