Gentoo compiles on installing, right? While thats always fine and dandy, as you get the source code right on the CD, I don't care for it that much, because the boxes I have to toss linux on are 266 or lower, and installing a pre-compiled Linux like Slackware takes an entire day (not exagerating..). Of course, for anyone that uses Linux as their main operating system, they will have a faster processor and it shouldn't be a problem.
