I retract my comment in lieu of finding out IPS displays are a 'must-have' for color accuracy. I am just very much a fan of 120hz. Clearly, TN is the way to go for me. I was returning to the site to edit this comment anyway to the likes of "Actually, to each its' own; I prefer 120hz". I am in no way attempting to mislead or 'troll' people. Especially not in a community like this.
Editing this post per James' edit of his post. Much better put - IPS is certainly in a different field than 120Hz TN panels, which are also quite awesome.
