One advantage of some Android phones have over their Apple counterparts is adding more storage. In the case of my new HTC One, I bought a 32GB (GigaByte) microSD card to load music and movies for about $20. At 0.6in high, 0.4in wide and 0.04in deep, a microSD card can currently hold up to 128GB. At that density, a cubic inch could contain 13TB (TeraByte). That's about $50,000 worth of DVDs in the size of 1/2 an ice cube.
