I am not talking about using launchers. What I meant was that Android users lack the ability to officially use stock Android to benefit from the true Google experience unless they purchase a Nexus device. That may also be described as a limitation or restriction of freedom. Most people are not fond of using custom ROMs, they tend to be buggy & are by no means a good replacement for the manufacturer's variant of Android. Besides, the majority of users lack the time to play around with their smartphones especially since most of them procure technology for improving productivity. By the way, some people jailbreak their iPhones to get rid of some of the restrictions placed by Apple. It's better for everyone to accept that different platforms are meant to suit customers with different needs. That is exactly why competition is a good thing.

Leaving aside the Android & iOS user experience, I want to present my views regarding why I think OS X is immune to viruses. Some people might recall that there were a variety of viruses for the previous generation of the Macintosh operating systems. So why doesn't OS X have its share of viruses? The answer is simple; OS X is simply better designed. Unix based & Unix-like operating systems differentiate between the system's & the user's files. Basically the user requires administrative privileges to modify system files. This means that when a person or an application attempts to modify system files in OS X, the operating system requires the administrator's password to proceed with the modifications. That is exactly why a Trojan horse targeting OS X relies mostly on social engineering. The virus or worm attempts to trick the user in to believing that it happens to be a legitimate application attempting to perform a legitimate task. If the user is intelligent or computer literate, he or she wouldn't be fooled by the virus's attempts at gaining administrative privileges in the first place.
Up until Windows Vista, Microsoft Windows made no distinction if any between the user space & the system's internal processes or files. Basically, every users had administrative privileges resulting in a virus or Trojan horse being allowed to carry out any modifications it desired by simply requesting a function to be carried out in the user's name. This combined with a variety of other flaws made Microsoft Windows extremely susceptible to viruses. People might recall that in the past all that was required to bypass the password prompt in Windows was to simply click on the cancel button. That itself demonstrates how devoid of security Microsoft Windows truly was. That changed in Windows Vista & the user's files & processes were finally differentiated from the system's files & processes. User account control in Windows is among some of the best attempts at securing Windows from viruses. Why do Windows machines still suffer from viruses? Social engineering is one of the methods used by illegitimate websites & applications to require administrative privileges, foolish users happen to be deceived easily. Another problem is that Windows still retains a lot of legacy code from the 9x era, that allows older viruses to run on even the latest versions of Microsoft's operating systems. The reason for the inclusion of this legacy code is to ensure compatibility with legacy hardware, it's in essence a necessary evil. There are other flaws in Windows' security as well, but these should be enough for now.
Getting to the subject of copying, there is a lot of truth in the fact that many operating systems do borrow from the user interface design of OS X & iOS. I advise people to notice the resemblance between OS X & Ubuntu 12.04's default Unity interface.
That should be enough to defend my contention. Of course, I could go in to a lot more details when it comes to discussing why OS X is superior.
Here is another hilarious video about Windows Vista copying OS X.
