It's not hard to manage either. One day that myth might finally go away.
They get better at hiding the complexities, but in my workplace (Windows XP) there are regulary occasions, when something stopped working and we have to re-run installers to get it fixed, even though the same patches that were causing the problem were applied to 20 virually identical boxes that didn´t have issues.
After a while Nobody really cares anymore. All they will tell you is: well, this happens .. just re-run the installer.
At home (Windows 7) is much less troublesome (it runs less software of course), but one box came pre-installed with a lot of crap (like Notons cloud backup ...) and it´s already hard to find out which app is causing the annoying behaviour.
Every OS sucks! And Windows is a brilliant example for that fact.
