I'm mostly interested in mac, but would be interested to see if it is different on Windows or other unix OS's.
I am an app addict and love trying out new applications. Every time I reinstall my operating system or get a new computer I try to resist the urge to download apps that I might not use. I do this because I think it will slow my system down even if I eventually delete them using a tool like AppCleaner.
Is this something I should be worrying about or is there no real basis to believe this?
