I've been reading on LCD devices since I bought my RCA ebook reader back near 2001. I go to the eye doctor once a year with my son (my son has a stigmatism) and get a checkup myself. I have no problems with my eyes and as I stated, I read mostly in low light or totally dark situations. I'm not saying this is true for everyone, but I will say that most of us here stare at LCD screens all day anyhow. So for the few hours you are going to read, you are going to get a device that basically only works in well-lighted situations (unless you buy a wedge light which in my opinion makes it far more if a strain on my eyes than LCD, or buy a attached LED light that isn't much better). The only advantage - for me - to buy a kindle would be battery life.
I've purchased so many devices to read from over the years, because I love playing around with them. From my own experience, the best devices were LCD devices. For good reading experience the eBookwise-1150 is right up there. The DT375 Tablet PC was awesome for multi-purpose use but the form factor was a little big and it was heavy. The Nokia N770 was the best of all. I could do so much with that device! It has a fantastic quality LCD screen with great DPI and resolution.
The Smart Q7 is very much the child of the Nokia Internet Tablet. It is slightly faster than the N8x0 series, completely hackable and matches the ebook reading form factor that I've been looking for. I'm not looking for a UMPC - if I was I would be paying a lot more for it, although not much more than an over-priced Kindle that can only do one thing. I just can't justify spending the money on eInk, especially the Kindle, when I can get so much more for the price. At the same time, I'm just not sold on eInk at all. I never have been. I gave it a 6 month shot with my Sony PRS-505 so it isn't like I didn't try the technology.
One thing is a fact - eInk just can't do some of the things I want to do on my MID/ebook tablet. If Apple does come out with a new tablet device I am so there. I'm willing to bet it won't be eInk.
In the meantime, I'll use my Nokia 770 and my Smart Q7 which I paid a fraction of the price for a Kindle to do a ton more with and I'll start saving for my Apple tablet...
