> Browsers could implement the same line breaking algorithm as used in TeX, but have decided not to for performance reasons. This is an odd reason — TeX was developed and runs on computers much less powerful than those commonly used in mobile phones. Yes, but not at a speed that many would find acceptable for formatting a web page, even on a modern computer. Nor need it be: you only have to generate your (La)TeX document while creating or editing it; a couple of seconds for a short document is thus tolerable. Whereas a web page has to be formatted by every visitor on every visit -- maybe several times if they resize their browser. It needs to be more or less instant.
