This is a far more significant move, since ePUB came out after the PRS-500, and PDF was around -- and on every eReader -- prior to the Kindle 2's launch.<BR><BR>Amazon is <I>not</I> supporting ePUB for the simple reason that they want you to buy from their store, not from somewhere else. <B>This</B> is the real lesson learned from Apple: tie your hardware to your store. Sony did that too, originally, but it couldn't compete with Amazon on content. So it moved its devices to ePUB, and allows purchase from any store that sells ePUB. This is how <I>all</I> readers should be, Kindle included.<BR><BR>Ars in general is somewhat anti-Sony. However, this is a case where Sony is the one making strides to an "open" format, while Amazon is actually locking down as tightly as they can.<BR><BR>-Pie
