There are only two reasons that one wouldn’t upgrade to Snow Leopard (and it could be either one, or a combination of the following).

  1. You don’t own a Mac
  2. You don’t have $129

So that means that if you own a Mac and you can spare $129 you will be upgrading to Snow Leopard. Let’s face it, the fact that the focus of this new version is just to improve the overall OS and not add very many features means that your time spent in front of your computer will inevitably be a better experience.

(I only wrote this post because of the recent trend of “Why you will upgrade to Snow Leopard” lists, the fact is, if you own a Mac your probably going to upgrade to Snow Leopard).
