Of course, we can't imagine our life without gadgets. I have several of them: a mobile, a tablet, a laptop. But I think that using gadgets a lot is not always a good idea. If you spend too much time online, you have no time left for real communication. Meeting your friends, going for a walk in the park—nothing can replace it.
My granny is 80. Last birthday we presented her a new mobile phone because her old one wasn't working. At first, she was quite happy but later she understood that it was difficult for her to get used to it. It took me a couple of days to explain to her how to type messages and take photos.
