I LOVE the idea of the K2 with the text-to-speech option on it.
I had a vision problem about two years ago. (optic neuritis in my left eye...had a ginormous blind spot obscuring most of my vision in that eye)
I used my computer's text-to-speech program (I hate Microsoft Sam) until I found a commercially made text-to-speech program (TextAloud) and just love how the text-to-speech programs work. Yes, they occasionally mispronounce words, but at least when I've needed to use the programs I can get past an occasional mispronunciation.
I still use my TextAloud program even tho my eye has pretty much recovered back to near what it was. I've had optic neuritis (nowhere near as bad) in my other eye once or twice since then (also recovered) and really enjoying being able to read and be read to by my computer. Altho I've only really used the programs with fan fiction stories or out-of-copyright books from the Guttenberg Project.
I cant wait to see my dad's K2 and see how the text-to-speech works. If I like it, I'm either trading my K1 for my dad's K2, or I'll be asking for an early b-day present and may send my K1 to my sister as an early b-day present for her.
From the small sample I heard of the K2's male voice, it sounds a LOT like the voices on the TextAloud program that I use. So, at least I already have a good idea how it sounds.
I dont see how it's a copyright violation... (TextAloud might give them a run for their money, seeing as how you can use TextAloud to make an mp3 of the text of a book, and then place it on an iPod, or post it on the internet. Something I dont think you can do with a K2)
