First of all, I know the 5.5G iPods carry the same relative dimensions as the original 5Gs, but my question is aimed towards my particular case. I carry my 4G 20GB iPod to school every day in a case and I've found it quite large. I'd like to upgrade it to one of the new 5Gs, especially due to battery life but also because of the reduced size. The 80GB version looks much better to me because for relatively little more you get a much larger capacity, nearly double the video battery life and the potential for backing-up information. The only real worry is thickness; the 30GB version is, iirc, 30% smaller than my current iPod but I don't know how the larger one compares. Considering the size is a somewhat important factor, what would you suggest? Also, on a somewhat unrelated note, what is the iPod like for playing ripped DVDs, for example The Incredibles. EDIT: Can anyone suggest a case that will not scratch the iPod through regular use? Most products have at least one review claiming that the case created scratch marks. I'd like one that covers the clickwheel too without restricting its use.
