When I first heard about the Nook, I thought, "Great, it can read all the 100+ eReader format books I've bought over the last 18 months on it!". After reading the announcements, I get the impression that B&N is moving to Adobe ePub. I hope this doen't mean B&N is abandoning eReader format. eReader format may not be up to some of the other formats, but I have no complaints reading fiction eReader books.
Before the Nook announcements, B&N seemed to be making eReader widely available with ports to several readers in progress, including EZ Readers and jetBooks; I own both. My fantasy

of buying books and reading on all my devices without format shifting seemed so close to reality. Several sites sell eReader format books so I have some freedom about where I choose to purchase books.
Now, I am not so sure. The EZ Reader version of the eReader software has dragged on since B&N bought Fictionwise and the Nook's Adobe ADE emphasis leaves me wondering if they are going to kill eReader format.

I don't object to ePub, but as a Linux user I do object to Adobe ADE. There isn't a Linux version.
I just want there to be plenty of eReader books available from a variety of sources to read on a many readers. Please B&N, don't drop eReader format book support!
