Yea, I mean now a days come technology is pointless to keep chasing for the latest but I also feel is a " conspiracy " tech companies purposely make your current device slow down while come out so call latest software update. Isn't Apple used to encounter one incident before? There is once the update is purposely drain your iPhone battery fast. Actually Apple don't used to be like this but now a days I don't know sometimes come IOS update or even come OSX always have this " feeling " they purposely also make your machine slow down thus you will thinking of getting a new iPhone, Mac etc. Likewise same for Windows or other tech stuffs.
