I don't understand the constant complaining about Irex and the 'missing features'.
I wrecked my Iliad V2 one time (cracked the display) but it was my fault. I paid 250 Euro for a new one and now I'm more cautious.
The battery lifetime of the the Iliad 2 was always over 10 hours. Even after three years the battery life hasn been very good. Of course more is better but be honest. Did you ever read over 10 hours in a row?
I want to buy a Irex 1000S because of it's great display size. If iRex finally closes I have to buy a Kindle DX graphite. And that means, no FBReader, no chms, no djvus, no custom programs.
And yes Irex hardware is expensive but I have got so much content out of my Iliad (waiting for the bus, train, doctor, ...) over the three years I wouldn't want to miss these devices.
The only reader which would be more interesting would be the skiff reader - but that was killed by the Australian Billionaire
