Kyle,
   for a distro that is trying to make one kernel image run on every 
possible type of hardware features like initramfs (and udev, modeules, 
etc) are wonderful.

however for people who run systems that are known ahead of time and 
static (and who build their own kernels instead of just relying on the 
distro default kernel), all of this is unnessesary complication, which 
leaves more room for problems to creep in.
