My most useless electronic thing is my mobile phone. Of course I have my own I can looking what my friends do, You don't must be rich to buy it. I'm spending lost of time for looking social media, I can play on it. I can hear music and recording films (tego nie jestem pewna), doing photos. I really like it.
