universal nandroid backup file?

[GixxerMan51]

I am going to be rooting my droid soon, and have a question about the nandroid backup. Arent everyones back-up the same, if so why isnt there a "stock" nandroid backup that everyone can download instead of going through the entire process?

Droid 2.0.1 nandroid full backup — www.TechIdiots.net - www.ElectronicInsanity.com
I found this just looking around, mabye a good thing?

thanks
