Question: What is the screen size?
Document: inexpensive and works well. I bought it for my wife when she said she wanted a cheap reader. I like the page turn buttons better than my Nook 1st Edition. The screen is very clear and changing font size is very easy.
This NEVER happens with the Aluratek. Each page is brand new with absolutely no residual letter imaging.As far as size, they're about the same except the Kindle is much thinner (about half) and the screen is a little bigger.When it comes to battery life, both are excellent, but I think the Kindle lasts a bit longer.I don't mind that the Aluratek has no wifi because it only takes a couple of seconds to transfer books to the memory card.
The screen, although a slightly odd colour, is sharp and clear and easy to read. The battery doesn't last as long as an e-ink device, but there's plenty of time between recharges. It does NOT have wi-fi, which for me is a plus, and it is not proprietary, so what you have on it is yours and no corporation is going to suddenly discontinue any of your books (as has been known to happen with a certain other device).
I agree with all the praise heaped by other people on this unassuming little device - it reads a huge variety of formats, even some that it doesn't claim to read, like html. You have some six different print sizes for most formats. It does quite well with PDFs for a small screen (though I would prefer mobi or ebook when available). It may take a few seconds to load some larger books, but the page-turning is instantaneous.
I haven't done that yet, so I can't say how well it works. >ADDED 8/28/12&lt; I finally bought an SD card and tried out the music player. It's pretty clunky. You can't really see more than a dozen tunes on the screen. There's no good way to scroll through the tunes and they aren't listed by band name. "Scrolling" is really slow, in fact impossible if you have more than a few albums loaded.
I highly recommend this product. This is the 2nd ereader I've owned. Unfortunately, I dropped my first one on a hardwood floor (without the case) and broke the LCD screen. When I bought a new reader, I researched a lot of different ones, and still came back to the Aluratek. I like the features it offers: books, music, pictures, and the variety of formats it offers. AND...I love reading it outside.
is better than I thought, I can use this reader in any place any time and read any book, faster, easily and let me keep with me all my favorite texts in a reduced place! sorry about my english... its not my native languaje!
i'm not in love with this ebook reader, but that's because i'm still in love with the printed word. this reader does just what it says it will do. no bells, no whistles, but that's what i was looking for.
great product.. shipped fast was completely wonderful... i like the color and the fact that i can play my music onit.
at this point I should have waited for another product. The battery is just flimsy. IT doesnt really last 24 hours, and when you turn it off after a couple of hours of usage (so you would have at least 20 hours more of life) the battery is down almost to the middle.I probably get another brand in December. Better save and read around before buying another e reader.
Answer: The screen is 3" by 4" inches.  I have really enjoyed this eReader.  I download the ebooks to an SD card.  Very good value for money.  Also a plus for parents is the lack of Wi-fi or 3G, which means they control the content for children.
