When you use CSS hacks that rely on browser bugs, you run into the possibility of those bugs being fixed at an unwanted time or other browsers showing the same bugs. The most beneficial aspect of conditional comments is that you are not relying on browser bugs when using them. Internet Explorer on the Mac uses a different layout engine and doesn't support conditional comments.
Conditional comments apply specifically to browsers using Internet Explorer's Trident layout engine, meaning IE-based browsers like Maxthon and Avant handle them like Internet Explorer does while browsers using other layout engines see them simply as regular comments.
They can cause Internet Explorer to ignore the markup between comments or to include part of a comment as if it was regular markup. Conditional comments are specially constructed HTML comments that Internet Explorer on Windows may treat differently from other browsers, optionally based on IE's version number. Luckily, as of version 5, it deliberately supports a rather safe-to-use hack called “conditional comments”. Due to its relatively poor level of standards support, Internet Explorer tends to be the subject of most CSS hacks.
