Yeah, if they need to be away for a longer time or they have people needing to reach them they can very well do with an old one that you can text or call on. Oh yes it is, considering its price and how easy they break but that's their business I assume and some kind of "upgrading" culture pretty much every year.
And no it doesn't but being antisocial and constantly hanging around your phone doing nothing of worth is a bit doing that, but that's my opinion

Yes I admit I spend time with my computer a bit too much maybe and yes I kinda regret it but yeah I mostly use it for some quality gaming and listening to music... and sometimes learning languages I guess haha.
Trust me, a lot of people uses those devices as babysitters.... That seems to be the main thing to do nowadays with them I guess regardless of how advanced they are(yes there are less advanced one for babies like smh).
