I'm still hanging onto my PRS-505 for reading (4 years this Christmas).
Have a Pandigital Novel Black - don't use much (only when my 505 needs charged) because it is too bright and the battery life sucks!
My son has an Aluratek Libre Pro but doesn't use it.
Then when Target lowered the prices on the iRiver Story and T1 I bought one of each. But they are both still sitting in their boxes!
