These days an average web page is 3MB -- the same size as the Safari download in 2003!Safari is a compact 3MB download that occupies only 7.1MB of hard drive space.
My first Mac was an iBook G4 purchased in Fall 2003. It shipped with Jaguar (2002) and Internet Explorer but Panther with Safari was released almost at the same time I bought it. I remember thinking Internet Explorer looked a hundred years old at the time, while Safari felt like it came from the future. Twenty years later I still use Safari 95% of the time. I won't install Chrome due to its auto-updating requirements but I do like the look and performance of Microsoft Edge, and I find Edge plays nicer with MailChimp (which I use regularly).
