Ok...so I'm thinking about getting an iPad but I'm not sure to get 3G or just WiFi? I want to do some work with it in school (WiFi), Home (WiFi), NetFlix (?), and regular surfing the web. Obviously the 3G + WiFi cost more...but the major killer is the monthly plans you have to order...Is 3G really worth it? Or with someone with my needs good with WiFi only? I have no idea how much 200MB vs 2GB of data charges would be so I don't know if 3G is worth it.
