Confusion

Rating: 5/10 (29 November 2014)

I was in my networking class and I was thinking....
When Lucy was able to access 28% of her brain she was able to control all kinds of radio wave. If she is able to access radio wave why did she need a computer to access the Internet(The first situation where Lucy and Professor Norman interact)??? And again she uses 2 laptops when she was on the plane flying to Paris, she was able to use 40% of her brain...
The QUESTION over here is "HOW COME SHE NEED A LAPTOP or in the second situation' LAPTOPS?????"
On the other side, I have no idea that how can some one be so smart after using some kind of drugs, well its a sci-fi movie so I guess that can happen, but after taking drugs someone could fly, that is just bullshit.
Otherwise the film wasn't so bad.
