Was syncing my morning news with Calibre, and after ejecting reader via Calibre and safely removing drive, my PRS-300 is no more. I've done hard resets, soft resets, powering down, long button presses, short button presses, usb reconnection. The hard reset brought my PRS-300 back about 5 months ago, but nothing is working this time. I wonder if the daily news syncing versus occasional book syncing is harder on the memory or what. Its stuck on the factory restoration screen, and will not let me press 5, return, or power down. It lasted me just over a year of constant use and abuse. R.I.P. Now to decide if I want to get the PRS-350.
