I use this product primary for the gym. You can surf the internet but the browser is slow. it is very easy to connect to wifi. Printing is a problem though. Most applications will not let you print to a printer. Sound Quality Great sound. I have hooked it up to the car, to headphones and to sound boards. It works well to transport music back and forth. However if you are using it without headphones it is not that loud. Performance Preforms without a lot of bugs. The hardest thing to get around is most wifi set ups are not fast. Battery Life If you are just using it for music and for about 1 hour each day it lasts for over a month. With wifi use it is dramatically shorter. Durability Lets just say I haven't dropped it but it puts up with me running and lifting at the gym. Ease of Use Very easy to use touch screen. It works exactly like an ipad in that fashion.
