I originally wrote this post in 2010, when I was looking for alternative ways to store and transport papers. I had my laptop, but due to its weight, limited battery life, and the LCD screen, an e-reader such as Kindle seemed like a good idea at the time. (Also, at the time of the original post, I had never owned a smartphone, let alone a tablet.)
Aside from the Kindle, are there any other electronic tablet or pads, or other devices that you'd recommend for this type of purpose? What are some of your experiences?
As for my self, I purchased a Pocketbook Reader 602 from PocketBook International four years ago. At the time, it seemed like a smart purchase, as it PBR handles a while array of file formats without needing to convert anything. However, I don't use the device as nearly as much as I thought I would.
The device itself works the way it should. It is a bit slow with the page rotation. And as user641 points out, the PBR can be a bit sluggish with larger files. The text-to-speech feature is completely useless when it comes to reading math. I tried utilizing the internet connectivity. While it is amusing to see websites in e-ink, in the end it's too sluggish to be of any use.
Here are a few things that I had originally thought would be convenient, but wound up being an annoyance instead.
Lack of Touch Screen Capability. I purposely chose the model that didn't have a touch screen capability. Reports of glare and the idea of getting smudge on the screen led me to that. However, the alternative is an extremely painful, unintuitive, tedious navigation.
Small Size. I opted for the small size of PBR 602 for its portability. While I have no problem reading novels, for math this is just unbearable. The slow page turn / search interface / zoom makes the problem even worse. Basically, reading anything that requires jumping from one part to another, looking up index or keywords, is extremely painful.
Note that the small size wouldn't be as big of an issue, if the interface was quick and seamless. For instance, I don't find reading math on my smartphone as painful.
I still use my PBR 602 from time to time. In fact, I go through periods where I would use it extensively. Unfortunately, its inconveniences prevents it from regular usage.
