The touch screen often takes multiple tries to hit a button and it often makes you hit the wrong one. It is very frustrating. The memory life is okay and you can get a couple songs and games before using up all your memory. I would seriously recommend a sony walkman (no touch screen) because it is so much better. Sound Quality Decent sound quality but I find my self plugging it in to a portable speaker more often than not. Performance Poor preformance. Battery Life If you fully charge it, it can be out in 45 minutes. Durability It has medium duribility but the screen scratches just by hitting it with your fingernail. Ease of Use It is a bit bulky but it is pretty good. Design The design is from the past. 2002 has come forth a decade. It brought the mp3 with it.
