It's not always fun being the middle child. Your older and younger siblings get all the attention and the special treatment. Rarely do you have anything to call your own – it's either hand-me-downs from the older sibling or stuff you have to share with the younger one. Sometimes, it's hard not to feel like an afterthought.
And if that's true of kids, then it's definitely true of smartphone lineups. Look no further than the Plus model in Samsung's Galaxy S series for a prime example of how the middle phone often suffers from a lack of attention.
