The Sony PRS-650 features a 6 inch e-ink touch screen, with 16 levels of grey scale. It has a built in storage capacity of 2 GB, which means it can store up to 1200 ebooks. It also has dual memory upgrades, which is unique in e-readers! It has a SD Port and a Memory Stick MS DUO. This means you can enhance your memory to more then 32 Gigabytes. This device does not have WIFI or 3G so you will have to download your content first to your computer and then to your e-reader.
You interact with your device via the stylus provided and can leave your e-reader on for up to 2 weeks without a battery recharge. We found from checking the unit out, that is very responsive not using the stylus and using your fingers to open up menus and options.
