I don't know what exactly do you mean by Android system. Does storage count? The idea of how applications aren't allowed to access each other's storage is very bad from the user perspective, for example. Permission model of Andorid is hostile to the user and is designed to the benefit of the manufacturer. It undermines the users' ability to take advantage of their computer but allows the manufacturer / whoever installed the system to have undue and unwarranted access to the device. My experience of using Android is very similar to using a corporate laptop configured by the least competent IT department of a large US bank: you are not allowed to do the basic and useful things, you are required to jump through a lot of hoops to have the remaining absolutely necessary things done, you cannot eliminate hostile functionality, you cannot be sure your personal stuff will remain personal (if it ever was...), it's a system that will automatically do things to you that you don't want done... Basically, using Android sends me back to the early 2000s when this kind of setup was typical for MS Windows computers given to employees in large US companies.
