For the technical user ,No,At least for large enough variety of phones. And as for the non-technical users - they always needed to pay someone or ask a friend when they wanted an OS install, so nothing&#x27;s different.<p>And if look deeper, Android is open-source ,so it&#x27;s undoubtedly offers much more freedom than windows.
