I currently have a 32 GB iPad 2, and am selling it to buy the new iPad. The dilemma I'm in is that I only have about 5 GB of storage space left. Because of this, I'm thinking of getting the 64GB model. However I'm not sure if I should really put out $100 more just for more storage space. I have 8 GB of music, the rest is pretty much apps. Some things I'm unsure of is if app sizes will increase due to retina updates, and whether the iPad OS itself will also take up more room due to retina enhanced visuals. I'm curious as to how much these retina visuals will have. $100 is a big difference in price, and I'm not sure if it's something I would really need. Any thoughts or opinions? Any advice or experience would be most appreciated.
