Note, the 150 dpi mentioned is for photos. Text and line art, there's a noticeable difference between 150 and 300 dpi.

I can actually read manga on my smartphone's 5.2" 1080p display. Not particularly comfortable but it is legible. Meanwhile, the same manga required zooming on a 9.7" 1024*768 iPad 2 despite the iPad's much larger display size.

That said, yeah, 600 ppi sounds like overkill. The reader would need a much faster processor, too, adding to the power consumption.
