Nowadays computers 'take' (zle slowo - tutaj PLAY) an important part 'of' IN our life.
In my opinion computers are OF benefit to us, but there are also people
who think that 'it' (nie mozesz mowic 'it' jak mowisz o l. mn - computers) 'is' (zmien to na l. mn) a 'niusance' (ortog).
First of all, a computer is really convenient and A helpful thing, it
often 'makes lot of work for us' (to co napisalas, to, ze one robia dla nas duzo pracy - a ma byc przeciwnie), like writing or searching
'informations' INFORMATION, which normally consumes plenty of time.
Another useful thing is that 'by' USING 'the' A computer we can do a lot of
activities without going out, like shopping, talking with other
people, even working.
On the other hand, 'it' (to znaczy co?) may have A bad effect 'to' ON us.
Or we can depend on computers and may fail IN our duties.
Summing up, computers are really comfortable, useful and of benefit
'thing' (niepotr) to us, but we must remember to use them in a reasonablE way.
