Very good tablet, I have my old ipad 3 Tablet sold because it bugged me slow, confusing and impractical app management, since ios8 only problems such as stuttering, crashes ... I was looking for a substitute, and came by chance on the Sony Z3. The app management is very clear and well adaptable against Apple, the sound is through the 2 speakers very well for a table, especially on a good set of headphones, a super sound. The display is very colorful and very sharp and Hel The Akk-term is also very long, and quickly recharged. A memory card slot is also available. The performance is very good, it jerky nothing. What I really like when you double-clicks on the screen, it turns on. It bothers me only that you can not outsource to the memory card apps, Samsung does that. My Conclusion: The processing, light weight, very thin, yet stable, plus the good performance, good display good tone convinced me. With only one negative point (saving apps on SD card is not possible) has led to a star deduction, saving apps on SD would be possible, it'd give full 5 stars.
