> The <font> tag has been wildly deprecated for years
Which means nothing. The 55 Chevy was deprecated in 1956, but I just saw one sell for $250,000 on TV. It still drives nicely and looks better than most cars sold today.
Granted browsers have come a long ways in standarization, but with the explosion of small screens (eg: phones), the FONT tag is making a bit of a comeback with mobile designers. The flexibility of allowing the device to determine the correct font via the FONT tag, means far less dreaded 'pinch' and 'zoom'. Having to zoom the screen is slowly becoming a known hazard to mobile programming and the font tag size (+ and -) suggestions tend to be more flexible and user friendly than CSS dictates.
Additionally, the FONT tag is always faster than CSS declared fonts. Fonts are always inline and render faster than CSS applied fonts. Additionally, css is usually external with require another file load or a cache if modified check.
