Help please it's really important

So for school I have to make a text, please correct my mistakes thx :) Please it's really important.

1/ A Mobile
A long time ago it was only used to call, it was unmoving.
Nowadays it is used to call, send text messages and do many other things.  It's portable.
In the future, it may change shape according to the situation. It might become a watch or a bulb. it will depend.

2/ A TV
In the old days it was a simple tv which projected images.
Now we have 3D TV. With it, we can have the feeling of being in the movie, while just being passive.
In the future, we could have the feeling of really be a part of the movie. We'll feel the actions and everything.

3/ An Mp3 player
Back in the past it was a record player which needed a CD, it was massive.
Then the mp3 player taken place, it has the same role but it's more little and it doesn't need a CD, but it needs a headphone.

4/ A GPS
A few years ago it was a map
Now it's digital
Later, it could bring the car directly to the desired place. 

Thanks a lottttt

Votre information au sujet des MP3 Players n'a pas raison. <<http://www.recovercamcorder.com/images/recover-deleted-files-from-mp3-music-player.jpg>> est un photo d'un MP3.  Au present, beacoup de gens n'utilisent pas les MP3.  Les iPods sont plus populaires.

Vos phrases sont tres longues.  En anglais, on n'utilise pas les phrases si longues.  Cela n'a pas d'importance quand on parle, mais en ecrivant, c'est tres important.  Votre vocabulaire est tres impressionant.  Bon travail!

(Je suis desolee si le francais n'est pas bon)
