So I just got my 4th gen and I'm loving it. But as we all know, the back is the most easily scratched thing in the universe. I need some help on deciding what case to get. My price range is about $20. I previously had a DLO clear hardshell case (for my 1st gen, when I still had it) that snapped on in the front and the back. It covered every single part the device except for the bottom (dock connector & headphone jack)...but no case covers that. I would like something similar to that. My preference would be a rubberized hard case, because If I got just a hard plastic case, it would probably scratch up the back since it would be hard plastic vs the back of the touch. I don't really want a softshell case because they don't really have the support to stay on. A two piece case would be nice...something with a front enclosure or a slide on case with a top piece and a bottom piece that lock together. The reason I want a two piece case is because with most of the case reviews (on amazon) theres at least 1 reviewer that says the case isn't completely snug and can easily come off. I'm pretty skeptical on the cases that just snap on the the rear becasue IMO is seems like they would just fall off (especially the silicone ones)-correct me if I'm wrong. So are there any two piece cases (back and front enclosure) that you guys recommend? Or are there any cases that you guys have that fit perfectly on the touch without a worry of it falling off? Thanks!
