With the way these apps are growing in size and content (Rage HD, Infinity Blade) it's only future proofing yourself. Imagine how disappointed you'd be with an 8 GB if you wanted those 2 apps!
8 GB is simply an anemic amount of space, and it doesn't give you much breathing room for anything. If you want to pay that price, fine, but have fun switching apps in and out.
