Will smart phone take the palce of computer?

We all can see that smart phone is becoming more and more powerful. And it almost can perform any function that computer can do. Actually I spend more time on my mobile device now,it is more comfortable and more casual. I don’t want to sit in front of a computer. If I can only shoose one ,then I will choose smart phone. Besides, you can take it everywhere, and it can work for much more time.
