True, and good points, all.
I should think that the display performance improvement can probably be assumed to be comparable between the Cybook3 and the rumored PRS505, though, so the comparison to the current Sony is interesting from that perspective.
The software is a different matter, altogether ... but ... I think I'm more interested in how the device performs than how the companion software does -- we already know we can live without the companion software if it's sucky enough.
In any case, I
really don't want to wait until the 505 releases in October (assuming it does), to find out more about the Cybook3!
