Hey guys. Today I am purchasing my new iPad and wanted your opinions. Should I get a 3g ipad and pay $25 a month for data? Or since I have an iPhone4 should I just upgrade the net to tethering at 4gig a month and use the wireless hotspot? I am leaning toward wifi version and tethering since cost wise I would be saving money. But wanted to get opinions on if this is good or not?
