The item has been lightly used and includes the tablet, stylus, usb charging cable, power supply, and original box. The construction quality is excellent as you would expect from a Made in Japan product. Asking 320 USD.
This was Sony's offering for corporate use to allow for easy reading and marking up of papers and documents - its initial retail price was $1100. It has a built-in microsd slot for storing ebooks plus has a built-in 4GB storage. It only supports PDF files unfortunately afaik. It can connect to wireless networks and retrieve files from WebDAV fileshares.
