For the casual user, rooting your phone isn't necessary. When you "root" your phone, you're basically enabling the "God" account on the device. The way Linux works is that the "root" user is the full administrator of the system. It can edit system files.
It's useful if you want to freeze/unfreeze apps, underclock your CPU for more battery life, etc.
If you browse the Market, you'll run across applications here and there that require root access. The best example of a "casual app" that requires root access are screenshot applications. Example: drocap2. You "shake" the phone and it takes a picture of whatever you're looking at.
Oh, and root is useful if you want to put a different ROM on your phone. Basically, a ROM is the same as the factory restore discs that came with your computer. People break down the android operating system and add/remove/tweak it to their liking.
If you look at the ROMS section of xda-developers.com for your particular phone and you'll see what I'm talking about.
