I realy like the hover-board because you always see and hear people fantasizing about using one just like they do in movies and books. They're also in my all time favourite time traveling movie "Back To The Future".
I also liked the Segway because it is an easy way to get around and if you feel like you are going too fast...you can just change the speed by leaning. They also just look really cool!
They are both quite similar actually!!!
