I love how MSCEs repeatedly show their lack of understanding of Linux.
The fact is that most of the software on my Linux Mint install is installed through the Software Manager, which is much easier to use than Microsoft's app store.
Where I do need to download to install, it is exactly the same in Linux as in Windows. i.e. Download and then open in the browser, the only difference is that I have to open with gdebi in Linux which is similar to the Microsoft MSI installer and pre-dates it.
The big advantage with Linux is that it has a better security model than Windows and in particular it does not have the extremely stupid concept of open = execute. I can surf the web an be reasonably safe from malware installing itself in the background.
