I'm wondering why so few modern web sites still use only PNGs for icons (but this assumption is just based my observation). So far I know, main reasons for using PNGs over SVGs are IE8 and that SVG uses more CPU power (but I don't believe this is any issue for simple 1K icons). I can see (and we currently use) many advantages in using SVGs, either when it's used as sprites, as images, or as inline
