Your judgement is based on the E Ink technology that is used in today's devices. Have you heard about PVI's touch panel, introduced only a couple of months ago?

Leading global ePaper display vendor PVI will announce new product Touch EPD in the 2008 Society of Information Display Exhibition in Los Angeles. “Touch Reader combines innovative touch panel technology and PVI’s existing e-paper product.” says PVI Chairman and CEO Scott Liu, “By humanizing e-paper’s user interface, we expect this new product to spur demands for e-books and solidify PVI’s leadership position in the global ePaper market.”

Unlike capacitive touch panels which requires the touch medium be conductive (such as a finger), this force sensing technology works with either stylus or fingers. The cost of the technology is competitive with resistive and lower than capacitive touch panels. In other words, the force sensing technology is highly competitive against all existing touch technology in the market, especially for the e-paper application.
