"But I don't use iCloud!"
Does not require a new Macintosh.
Works with older versions of OS X.
Far more recently updated than than Firefox or Safari for pre-OS X 10.5.
Works with Web sites that only accept the most recent browser revisions.
Lacks some of the bells and whistles of the latest mega-browsers.
Works better than Firefox 3.6.28 or Safari 4.1.3, which are the most recent revisions that will work on a non-PowerPC Mac.
