Had to upgrade from a 16 Gb iPad (3 I think) to the 32 GB because every time you get an upgrade to an app it eats up more memory. Now my 32 GB only has about 4 GB free. My discussion question is, "Doesn't an app upgrade ever get more efficient and actually reduce the amount of memory used?" Will I need to upgrade to the iPad Air 64Gb pretty soon. I can't afford it! Let me know what you think.
