Actually 5. But only the first and last one was not handed down to me. I haven't really used them much, though. They mostly stuck around because I needed one and others just gave me their old ones at some point. Though, this year there were some technology involving changes that made me buy a new one. Otherwise I would still be using that one that, by this point, is already over ten years old. xD
Do you have special apps on your phone? (Not the usual phoning or messaging stuff but rather things like drawing apps and whatever else you can get nowadays.)
