I've been looking into buying an iPad lately and don't really know where to start. I really don't have that much money to spend so I've been thinking about buying old or refurbished iPads. With the introduction of the iPad mini, that may also be in the mix also. So my question is. . which model should I buy? Keep in mind that I would probably buy a used or refurbished version of the iPad 2 or 3. Apple is currently selling their refurbished iPad 2 for 320 and their iPad 3 for 380. I'm an Econ major so I'll mostly be using the iPad to take notes as a lot of the courses involve graphs. I'll also be using it for textbooks and readings. What do you guys think? Is the iPad 2 too outdated or is the iPad 3 not worth my time?
