I used eReader going all the way back to its Peanut Press days. For Palm you just couldn't beat the format and content. Then I moved to iSilo. Now, my Palm and treos are long gone in favor of my trusty (and reliable) Blackberry and PRS-500. The books I bought from eReader are all stranded in unsupported format limbo now...sadness. My PRS-500 is now my default book reader. If it can't be read on teh Sony reader....it don't get readed. ( and yes...I meant it to sound like I typed it)
It's format wars all over again. Unfortunately, Sony (as is their custom) won't support a format unless they can make money on it...and vice-versa.
Can't they all just get along?
