I think this is the wrong approach to take for this issue – I myself only have the PRS-500.

When I bought my PRS-500 I knew I was an early adopter, I also knew that when it comes to technology things move quickly – how many people keep the same mobile/cell phone for more than a couple of years before upgrading?

I’ve had my Reader for almost 2 years now, yes I would love to have ePub support but, as Roland often says, “the world has moved on”.

Although my reader still works perfectly I will likely want to buy a newer reader sometime in the next 12 months. If I choose a different make, it won’t be because of Sony’s lack of ePub/re-flowable PDF support for the PRS-500.
