I am a creature of habit... or maybe I just get easily stuck in ruts?  I have long resisted moving over to a 64-bit OS because of troubles I've encountered the last time I tried it.

A couple of years ago, I accidentally installed a 64-bit Linux distro.  It correctly identified I had an AMD64 CPU and quietly selected the right kernel for my hardware.  I never noticed that it had done this until I wanted to add multimedia support and a few browser plugins.  Then.. the chaos of mixed architectures began.  It was messy... I didn't like it... I reformatted my root partition and went back to 32-bit and have been there ever since, carefully selecting the 32-bit kernel with each OS upgrade/reinstall.

Recently someone brought it to my attention that the specific objections I had from past experiences are long fixed, and it should be no issue at all to install 64-bit. 

Hmmm do I dare leap out of my 32-bit rut?  I already have my 64-bit install DVD ready to go.. just have to suck it up and go for it I guess.
