The way this industry is growing and the way technology is improving, I wonder we will not see this much big heavy machinery if you go back in 19s, This is not big in front of the machinery that was used that time, do you remember the size of the first computer? it was big as the size of the room, and you can keep the laptop with you anywhere you want, and event you have the laptop in your selfphone and you can keep it in your pocket, technology is advancing and getting shorter and shorter. Thank you so much for sharing this wonder machinery images with us, it's looking practicle and wonderful.
