Default What do you think about cluttered smartphone

What do you think about
Phone that install Facebook twitter Instagram line Skype etc
and all of them got their notification on

Seriously I hate them

And guys that got cluttered smartphone often complain about its being slow low battery etc

I don't own apple device but I don't know how they manage to make over 9000 app open all at once (while they are in..... Task bar?) (more like tray)

Most android phone that I borrow from other students are cluttered same for idevice but it's got faster speed
