A gun in the hand is better than a cop on the phone.

A computer lets you make more mistakes faster than any invention in human history - with the possible exceptions of handguns and tequila.

USMC rule # 23 of gunfighting: Be polite, be professional, but have a plan to kill everyone you meet.
I can understand your feeling of being overwhelmed. Here's the explanation.
Think of OEM computers...
You buy a computer from Dell and they give you a "Windows Restore" (or w/e) disc. It contains a copy of Microsoft Windows™ with it which is loaded with a bunch of extra applications and utilities.
Imagine if Dell also made it so you didn't have admin access on your computer so you couldn't delete those stupid apps that are slowing down your computer. ROOTING your phone helos you be able to remove that crap (and more)
Sometimes dell also replaces a bunch of the screens, like the login screen with their logo feces. You can't just remove this, can you? And what's more, imagine that dell also replaced some of the system files with their own GUI which is ugly and runs slow. WTF?!
Ok, so you go buy real Windows without the taint of evil in it and go to install it. You install it, reboot, and your computer tells you that you're running software that isn't allowed and won't boot until you reinstall from Dell's CD.
That's what Droid X is like. Moto put crap on it and modded the OS. They locked the BOOTLOADER (thing that loads the OS) and made it lock you out of your phone if you go to install a non-Moto OS on it (ie stock android from google's site)
I was worried about giving up my original Droid and all the custom ROMs I could load and replacing it with the Droid X. Now with all this in progress I can't wait for the Droid X to arrive. So hopefully any day now it will be delivered to my door steps.
