and you don't need any special process to manage it.

You're speaking of apt/packaging like it's a bad thing, when it's awesome. Want to download a new OSX or Win app? Open your browser, hunt it down, in the case of Win, figure out if you can trust the site, download it, open the downloaded item and do the install dance, and then have it stay sessile on your system, never updated... unless it has its own phone-home system - and now you have more crap on your system.

Want to install a package with package management? It takes literally seconds plus download time. Package management systems are all about doing away with managing complexity.
