3M invested in txtr last year, so this makes a fair amount of sense. 3M saved the expense of developing a new device and txtr recouped the cost of developing a device that couldn't be sold on the retail market.
I don't have any specific details on the current device (edit: all 3M gave me was the image), but I do know that the txtr Reader was based on a 6" E-ink screen. It had Wifi, optional 3G, Bluetooth, g-sensor, a vibrator (for feedback), and it had a swipe pad in place of a d-pad. It's not clear what details will be n the final model.
But the most important detail on the txtr Reader is that the design is 2 years. Compared to the current market, it is both underpowered and overpriced.And now 3M will be selling it to a small niche. They will have to take a loss or charge far more than the thing is worth.
P.S. I'm also told that txtr are still having trouble with it, but I can't confirm that.
