Today I returned mi iPad Mini to Target. Yesterday I was using it and was trying to convince myself that it was the perfect screen size. However, I got a headache after about 5 minutes of use. This morning I did the same and again headache. Must be the small screen size...straining my eye sight. Who knows... Anyway...I am debating between the iPad2 or refurbished iPad3. Is it worth getting the refurbished iPad3? I noticed I can buy and pick up at the Apple store... Also, I got the protective cover for the Mini through the online Apple store. Is this something that I can return at one of their walk-in stores?
