How do you find the keys on a keyboard without looking at the keys?
Blind people do the same thing other people do. Practice and remember.
If the keys are all flush like Motorola devices, they simply put a dab of glue on frequently used or landmark buttons.
In some cases I think small unmarked buttons bother sighted people more because we expect to see visual cues and rely on multiple sources of input. If one lacks information the whole system becomes debilitated. Yet at the same time we fumble for car stereo controls, signals and gear shifts in the dark without a second thought.
Complicated non-speech menu trees and multiple buttons with frequently changing functions cause trouble. But then again, they irritate me as well.

I like this device as well. If it comes to market in time, I'm going to force my siblings to chip in an buy one for my dad for Christmas. As a lazy, infirm blind person he could use it to go along with his voice gps, ipod nano filled with audio books, and talking laptop that help him sit around the house all day and do nothing since he's apparently incapable.

Uncool title.
My father has been blind his whole life. He uses devices like this on a daily basis. Actually, he's the CEO of a mid sized business. Niether lazy nor infirm. You missed the boat on who this is marketed towards.
They're not "presenting" it as a necessity rather than a luxury, it IS a necessity for those who would buy it. Not everyone can afford to pay someone to sit and read every piece of paper that comes by, and then follow them around with a file folder and reread a page when they feel like looking back at a document.
They're all expensive because the market is so small. I saw the price and thought "reasonable."
The text to speech is inhuman because machines can't understand inflection and interpret meaning. That it pronounces accurately IS stellar.
When you're going to be incredibly flippant about a device, it helps to actually research the market it's intended for.

"who's really buying this with the Pre just $50 away?"
People who don't want a slider that twists like a turntable after a month. Or people who have pudgy fingers who despite the fact that the device uses the same buttons, can not use them with the spacing on the pre.

@Tommo:

I don't know about fixing the economy, but speakers sure do fix my... sound, noise, something or other.
