With the slow refresh rate of e-ink, a physical keyboard is the only way to go.
And once you have the keyboard, what do you really need a touchscreen for? Scribbling? Taking notes? Maybe, but the slow refresh rate of e-ink makes these things feel clunky at best -- I know, I own an iLiad. I like it, but I almost never use the stylus except to do things that a button could do just as easily. Meanwhile, the trade-off for touchscreen capability is shorter battery life and substantially higher price. In my opinion, it's just not worth it.
Remember that the Kindle 1 had that little LCD selection bar? I thought that was a brilliant design choice. E-ink at the time was so slow that moving an e-ink menu bar felt clunky. The LCD bar was slick and fast, and they could use the e-ink display for the static menu options.
Anyway, the point is that the normal UI design paradigm just doesn't work with e-ink-based e-readers because the refresh rate is too slow. The biggest challenge when designing a reader today is figuring out how to design the UI so that the user won't get frustrated. It's very challenging. All modern design concepts assume a fast refresh rate, so there's no real prior art to work from.

Irex has well proven you don't need a physical keyboard. A on screen keyboard or handwriting recognition software is plenty sufficient. We're not writing a novel here...
A touch screen obviously adds ease of navigation, ease of annotation, more versatility as a digital pad perhaps...
Lets agree it would not be friendly to price or battery life. But to ignore its benefits is ludicrous IMHO. And to argue from a usability standpoint? As if a touchscreen is not obviously more intuitive and less frustrating? Would it be more convenient to scroll to the bottom with the janky d-pad or simply touch my option. Hard choice this one...
Edit: And anyway I wasn't suggesting they take away the keyboard. They can leave that silly thing. I just think a device this big is screaming for a touch screen interface.
