I've been using my Elonex 511EB for over a month now, and I have to add here it gets full marks for battery life. I charged it fully on the day I bought it, 10th March, and it finally ran out of power on 17th April. In that time I'd read four novels and 6 copies of Asimov's SF magazine, including the double issue. That's about 2,500 ePub pages, or 7,500 page refreshes. Given that I was also going back and forth and navigating around the device, I reckon that fully supports the quoted battery life of 8,000 'pages'.
On top of that, I looked at some pdfs, listened to a couple of podcasts, and a few tracks of music, recorded a voice memo and played with the text to speech.
I can live with charging it up once a month!
