The advantage of the dedicated e-book readers is that they only use energy when changing pages. The display requires no power to continue to show whatever page you are looking at. That means that they do NOT flicker.
I don't know if the contrast is adjustable, but they are monochrome and I suspect not.
BUT the contrast is not so good as an ordinary book. There is some reflection from the surface of the screen depending on lighting conditions. Maybe it is a bit like dealing with glossy paper - which gets on my nerves sometimes.
The Kindle I looked at had the page turn button on the top edge on the right, so when you pick it up with your right hand about 50 pages go past. Apart from that it was an object of desire.
Personally I prefer to read e-books on my pda, which I already have to hand nearly all the time, and I can at least adjust the brightness, but it uses energy all the time to run the backlight so battery life is nowhere near as good as for a dedicated reader.
