A few points from this article...
The screen is no "retina" display, but text is clear and smooth
Neither is the iPad, so why comment on it not being a retina display? No, it's not as good of a screen as the iPhone or even the Google Nexus, but neither are any of the tablets...
An e-book reader at heart?
Erm, no, it's a tablet - no e-book reader has a battery life less than a week, let alone a month (like the "proper Kindles"
Like most Android/iOS devices, it CAN be an e-book reader, but it's not its main function, at heart it's a (limited app list) tablet, meaning it is meant for a little bit of browsing, a little bit of media consumption, a little bit of reading (short term), and a little bit of messing about with apps - I'd REALLY like a review like this to be done on the iPad, and compare it to REAL e-book readers... just because this is branded "Kindle" doesn't mean it does exactly the same as other Kindles, it's just a brand name!
none of the films I dropped in were detected by the tablet's Video section
Maybe if you drop them into the correct folder, it might help - did you look for the right folder or just drop them in the root? At heart Android plays videos from a "gallery related" folder, and if you put anything outside of that then it'll be ignored (ICS reads from "Movies" too), also, did you put them in MP4 format? Complaining about user error on putting videos on a device is hardly a real complaint!
I get sick of people comparing devices with things that they're not meant to be compared to, like a review I read of the ASUS Transformer to laptops, when it's a slightly more powerful tablet that can have a keyboard...
