Apple killing Windows performance by filling up your hard-disk with junk
A picture is worth a thousand words… And Jobs is speaking about Flash and Adobe and MacOS-X performance. Microsoft should do the same, say out loud what crap third party practice is many times making Windows in the real world crawl to their knees. One of the culprits is Apple’s installer (Apple Update especially) leaving tons of garbage on your hard-disk after each QuickTime / iTunes / Safari software update and installing other (not needed for the average Windows user) side-software without warning you first like the Apple Mobile Device Support and Bonjour services.
And of course Symantec too, leaving a 230MB of virus signatures (definitions) on a machine where their antivirus hasn’t been used for years now. In my personal opinion the root of most of this uninstall garbage evil is InstallShield (also the root of most of those lengthy installation/uninstallation times together with the Microsoft Windows Installer technology and it’s internal homebrew SQL engine [yikes!])
