Not just rooting. Rooting + installing vanilla Android increased my battery life significantly over Motorola's version of Android. As far as the rooting process goes it is fairly easy.
One Click Root for Windows
Here's the Windows version. Facelessuser pushed this through and worked his magic. Give it a try. Very exciting stuff. I haven't used it yet, but according to him, it should work!
Download here, Ver. 2.1.4:

Instruction for Windows:
1. Extract the folder from the DORoot zip file to your desktop or something. You should be moving 7 or 8 files into the tools folder.
2. Install Motorola Drivers
(Tip, to stop the launching of the Verizon/Motorola site, go to the MotoConnect icon in the bottom righ, right click, when phone connects, nothing.)
3. Make sure you phone is in PC Mode with USB Debugging enabled
PC Mode: Notification blind -> USB connection -> PC Mode
USB Debugging: Settings -> Applications -> Development -> USB debugging
You need USB debugging icon showing in notifications. Try Charge Only if you can't get PC Mode to show USB debugging.
4. Double-click and run doroot.bat
5. Let it run.
6. That's it, you are done.
Motorola Drivers (if you are using Windows) which can be found here:

Many thanks to facelessuser for working his magic!
I had to try the method about six times before it finally took. It varies according to the forums where I got this. Some people saw success on the first try, others it took a dozen times.
Remember, this is ONLY for the Droid 2 and Droid X.
There are other one click methods for other phones and versions of Android.
