The zoom function is in one of the future software versions (they know it's missing and are working on it, it's not something they never thought to handle). E-ink itself is not really fast reacting, so I guess zoom will take 1-2 seconds to do at its fastest. On the other hand, quality of reading is absolutely great, unbelievable, and as Sischa says, I am more than happy with it for reading, I don't plan to surf the net or use it for anything else, as far as reading goes, it really works for me.
