I know this has been discussed before, but here I'm interested in a single angle: the resale. Basically, I have a feeling I will sell the iPad and upgrade next year when they refresh it. I might be wrong, but I have a feeling they will add a front-facing camera at that time. I will definitely get a WiFi + 3G (or 4G or whatever) at that time. But for now, I don't *really* need 3G, even though it will be nice in some circumstances. However, when it comes to reselling it and buying the new iPad, which will be the best route to go? Save money and get the WiFi then sell it? Or would the WiFi + 3G keep value better than the WiFi one does? Thoughts?
