A/ Near kindle paperwhite quality front lit screen
B/ audio capability and built in speaker (or Bluetooth).
C/ 8" screen or smaller
D/ known to work with Ivona TTS, or at least, not known to not work with Ivona.
I'm going to use it for epub and Mobi, RSS, light web surfing, and to use TTS when my eyes are tired.
I have a spend-it-or-lose-it budget to buy this device, so I don't care how much it cost -- as long as it's not over $500
Thanks
