I am looking for the ideal for how I will use the tablet, the extra $100 isn't that bad but if the new iPad isn't worth it I won't want to dish the extra money out. Most of what I will use this for is note taking and *Streaming videos over wifi at medium signal strength range*. Since I plan to buy the base Wifi Model (I can tether from 4G phone), will the potential Wifi issues hurt me with the new iPad. Also I'm slightly concerned about the heat, I realize its within "Reasonable Levels" but I don't really want to deal with that. Is the overheating issue primarily with 4G models or all of them? Which one do you think I should go with? Input is really appreciated.
