One of Sony's most recent sought out devices, the PRS-500 eBook reader is going to be delayed once again. Sony Electronics brought the PRS-500 with them to CES this past January and had announced a Spring 2006 launch but then pushed it to the summer of 2006. Sony is now saying a fall launch seems more likely.

The eBook reader used to be listed on the Sony Style merchant site, not for purchase but rather for pre-order. Soon after that the options were changed to an "Update Me" status to take interested parties' email addresses down to let them know when this thing actually came out from under the rock it has been jammed under since this past spring season.

Many have been looking forward to the PRS-500 and many others, like the recently launched and now shipping eFlyBook which is built by iRex and marketed by ARINC. Though the eFlyBook has launched and is already being sent to lucky consumers, it weighs in at about $900 including a cart load of aviation data which would otherwise cost around the same price. Sony's PRS-500, on the other hand, is still priced at $350 which is a number that is a bit more practical for the day to day user.
