The 8, 16, 32, and 64 which is quoted in the first comment is actually the storage, and the i Pad Mini has only 512 meg of ram which is less than the i Pad and same as i Pad 2. i Pad 3 and i Pad 4 have 1 meg of ram installed. Supposedly the new Samsung Nexus is going to have 2 gig of ram and probably either a dual or quad processor. Probably most people can get along nicely with 32 gig of Storage. However if you are going to keep a significant amount of mp3 music and .jpg photographs, you might take up half of that with there two types of files. I currently have high speed internet, so can use streaming audio which means that I could get along without mp3 music. Also some of the Android Tablets have the provision to extend storage by another 32 gig, so that would give you 64 gig for the operating system, programs and data. If you have 100 gig or more of programs and data stored in your current computer, you will not be able to have that much in a Tablet. In the i Pad mini, 512 meg of ram is all you can have installed. With Android Tablets, the ram is fixed by the machine and usually the storage too except for the models that let you add to that with micro SDs of 32 and 64 gig. Estimate what you are going to need to do what you want to do, and that should allow you to select a Tablet that will provide the resources that you need. Also, remember the i Pads do not allow you to add additional Storage. What you buy is what you get.
