My wife use the big size, I use this smaller one. I bring it to office for daily notes, and reading as well day and night too. Backlight is nice feature. Apps work fine. Some setup is a big harder or need to figure out, but with some learning it is easy to use and it become easily your daily companion.
I bought both size. We love both of it. Use all features. It gives exactly what you need if you search for E Ink tablet with lots of extra. With continous software upgrades these tools going to rule market easily. I would love to try a keyboard for small and bigger borther as well. However not essential. It is good as it is.
I gotta say. I kinda love this little thing. I have an ereader already but this is great for just carrying around (if you're not sitting in one place). It works so well and it's cool having the android and google play ecosystem. I put a popsocket on the back and it's so light and easy to use. I found that I actually end up reading more and faster (I think it's because the narrower column width). Also, I have dropped this from quite a height and sat on it without any cover (don't do this), but it still works perfectly so it's actually pretty tough. I would definitely look at buying from viwoods again in the future.
