You assume all scripts are about malware, hence the Windows only usage?
I use NoScript because it makes browsing the web so much more pleasant. I hate websites running all sorts of extra scripts to open up pop up windows, pup unders etc, or deciding to redirect me to ask a survey, or to play an audio or video track automatically etc. Many sites excessively use scripts in their efforts to monetize their traffic. I block all scripts by default and only temporarily white list those I need to, to make the part of the site I'm trying to use function. If it's a regular site I visit, I permanently white list it.
Combine NoScript, with AdBlockPlus and a cookie manager like Cookie Whitelist, and Better Privacy for those real sneaky companies like Disney who use zombie Flash cookies that hide from the regular cookie management, and resurrect themselves to carry on tracking you. You forget how obnoxious some sites are when you visit them in browsers without that level of control and blocking.
