literally this is the future of software. just think of every program that has absolutely useless features which are heavy on the CPU and make your device get super hot for no reason. totally retarded. what we need is a blank slate – a tabula rasa, if you will – from which the perfect, customized UI can be conceived of by the user with ease.
on a mobile phone, this could mean that the device itself only has the most basic calling/texting functions pre-installed, and from the moment you turn it on, the rest is yours to do as you wish.
apple isn't even thinking of such a thing – it is inconceivable to the corporate hive mind – and it shows.
