I recently got my eBookwise. I was planning to buy a sony reader. But someone on the forum was selling their eBookwise at a great price and I couldn't resist! I love this device. Now that I've used it for a few weeks, I'm pretty sure I wouldn't be as comfortable with the sony reader. I like the sturdiness of the eBookwise. I don't have to handle it delicately for fear of damaging the screen or any of the other parts. I didn't think I would ever need the rotating screen feature (I'm right-handed). But it turns out the feature is very useful when you are lazing in bed and reading!
Bottom line I don't see myself going for another device unless this one is damaged beyond repair! Given the reputation of the eBookwise, I don't see that happening for a very long time
Although I have to admit, I
may decide to get one of the e-ink devices if the prices drop drastically in the future. Just for the experience!
