Ok, I believe this was a necessary topic to address.
Neo-Zombies vs. Old-School-Zombies
There are quite a few differences: Looks, speed, diet.

Looks:
The old school zombies looked, well mentally challenged, and who are we kidding? Not that frightening either.  The only thing they had going for them really was the obvious fact that they are going to eat your flesh, they're dead, and you will be dead soon.  And oh my!  Lets not forget about the HORRIBLE bags under the eyes!

Little Miss Kyra Schon here looks as decadent as ever don't you think?
I got the chance to see her, and join in on a Zombie walk with her this past summer of 2010
So yeah, we get it, Old-School zombies?  Cool for dressing up as, aswell as cheep, but definitely far from scary.  Now lets take what many have decided to dubb as 'Neo-Zombies', a term used for the new aged group of zombies that has infested our culture, in movies, books, television, those you're screwed no matter what you do kind of zombies.  Now these things have quite a few different looks:
Resident Evil Zombies
Even the digital depiction of them are flat out terrifying.
Now, there is quite a few quarrels going on about this creature, Seen in I am Legend
Some don't think they are zombies, but by golly, look at it.
It screams I ate your flesh for breakfast
Okay, not many people have heard of this movie, Zombie Strippers, came out in  2oo8
If he doesn't die from a heart attack soon, I'm quite sure she will tear his pole off first

But no matter how you look at them, you will always be terrified, but don't worry, you won't be scared for long, these guys are wicked fast.



Speed :
Neo-Zombies are the kind of creatures of the night that you have nightmares about.  These guys put cheetahs to shame, no matter what.  If you were caught in an alley with one of these things, you might as well not try, just strip, right there, hopefully you will be dead before your shirts completely over your head.
If you can't outrun this.
You don't stand a chance.
  But now, if you were to encounter an old school zombie in say, a cemetery, the only chances you have of dieing in said cemetery, is if your wheelchair falls over and you're a paraplegic.  I'm sorry, but thats the cruel truth, handicapped people go first in ever zombie invasion.



Diet : 
It was said in one of the most know old-school-zombie movies that zombies ONLY eat flesh, you know that stuff that we call skin?  Often times covered in acne, freckles, and glitter in some districts.




Well somewhere along the lines, someone took A Christmas Story to heart, and realized that they had to make zombies more gruesome, since speed wasn't going to cut it.  Some twisted son of a gun decided to make zombies not just crave your skin, but you're ENTIRE being.  And I'm not quite sure where the whole "Braaaaains" thing came from, have you ever watched a zombie movie, and the news warns the unfortunate people that "Careful out there, they just want to eat your brains! Wear a helmet!", no.  No, you have not.

Randy, will you eat? There are starving zombies in China! 




So yeah, as you can see, plainly, there are quite a few differences in the two types of zombies.  I'm voting for the president that will promise Old-School-Zombies will infect the populous after we find the cure for canceraids, because I don't know about you, but I would definitely like to be able to last around long enough to see some people being chased by slow zombies, and get caught by them.  Send your kids off to school, and arm them with old records, sell them like trading cards, make television shows about it, videogames!  Make the current zombie issue into a new generation of pokemon.  I hope that you have been able to take something away from this, as I have.  

And if there are any facts that separate the two types from each other, please feel free to comment. (:
