Boyue T62
I just rooted and set up a Boyue T62 for an avid reader. I used an exposed module to have the page up and page down buttons trigger Tasker tasks that input screen taps, making the buttons work in pretty much every reader app. It misfires on occasion, but the user says it happens so rare that it's not even an inconvenience.
The experience of reader apps as reported by her:
Built in "Books" app for non DRM books - Works flawlessly, but finding books stored in the card isn't as user friendly as it should be.
Cool Reader - works great after you tweak the options
Nook - Nearly flawless, but there is bug with the front light. If stuck on, use light icon in the tray to turn it off. Very minor inconvenience. Page turns are slower than an actual nook, but still well within reason.
Kindle - Sluggish, but once a book is loaded, works great.
Kobo - Unusably slow, but who uses Kobo anyway?
Various "Free ebooks" apps - most work great!
PDF - not tested yet.
Other apps useful on eInk
Flipboard - Usable
"Internet" - Great for pages that have a lot of text.
Built in Email - Flawless
IHeartRadio - Flawless, excellent for music to read to
Keyring - Set up and Tutorial look like crap, but it works flawlessly after that. She had this app on a hacked Nook before, and she has yet to find a barcode scanner that can't read an e-ink screen!
Google+ - Fails to install
Google Plus mobile site - works well
Dictionary.com app - Fails to install
Play Music - Fails to launch
Facebook Lite - works well
Facebook regular app - not tested
Google Keep - Works well, but color options, obviously, are quite limited. She just uses what we assume is the default yellow, which displays clearly.
Rounder - Looked AWESOME with the victorian corners she likes, but it interfered with the tasker set up I used for the page buttons.
If you're interested, e-mail me
Miakoda@KlatchNet.net, and I'll give you the code and screen coordinates to use in tasker for the buttons, and the name of the exposed module I used to connect tasker to the buttons. I don't have the reader in front of me, I'll ask her for it for a second to get that for you. It's configed so the page turns are screen taps on click, volume on long press. The refresh button is standard refresh on press, standard back light toggle on long press, and brightness options on double press. Power key is standard power on press, power menu on long press, and screenshot on double press. Interestingly enough, screen shots are color when sent to a color device. I wasn't expecting that. The double press for the backlight options is a fantastic work around for the backlight bug in the Nook app.
When I see her, I'll see if her boyue supports USB host.
