I am writing to you after reading the article about the influence of computers on printed books. I want to share my opinion with you and all readers.{1}

Nice start, which clearly states your reason for writing.

Article error

{***}internet{2}

Normally, we say 'the' internet.

electronic form of what we read{3}

This sounds a bit awkward. I suggest something like:
'The biggest pro/advantage of reading in electronic format....

multimedial {4}

Word form - The usual form is 'multimedia'.

you look {5}

Verb tense - 'you are looking for' would sound more natural here.

. A funny pro I thought of is that your pet will never eat your reading matters.{6}

This sounds a bit like an afterthought. Is it a serious point you want to keep in?

convinced to using {7}

Wrong or misused preposition - 'Convinced' usually goes with 'of' or 'by'.
Examples:
'...convinced of the need for electronic books.'
'...convinced by the arguments for using electronic books.'

bore yourself {8}

Word form - 'get bored (to tears)' would sound more natural.

near {9},

Word form - 'nearby'

amount{10}

'number'

got used to {11}

Verb tense - 'are used to' or 'are deeply attached to'

{12}

Put a full-stop or at least a semi-colon here.

They (13)

Vague reference - I had to read this twice to make sure what 'they' referred to. I thought it was people, not books, at first!

'to' would be the best preposition here.

I partly agree with the writer of the article

Well-constructed phrase or sentence

one can never fully foresee

Good choice of vocabulary

Missing word or words - 'the situation'?

Article error

Using

Verb tense - 'to use'

now{17}.

Or 'at the moment' or 'for the time being'.
