I would like to say the KINDLE HAS LANDED, THE KINDLE HAS LANDED!!!
This will get updated later but ...
Downloading via wifi is easy! I've managed to download a book! You can download without wifi, by downloading to your PC and then copy to your Kindle which shows as a USB drive.
It is a rather nice size. And its slim and light. This should give you an idea of size.
Readability? Excellent indoors. I took it out into the bright sun and it was fine. Yes you can get glare if you move the screen to the right angle BUT it was very readble in direct light.
The only annoying thing is that I have about 3 months of nomral books to read!!
