Resolution is only thing that matters. It tells how much information you can cram into a screen. If pixels are too large move back. If they are too small move closer. If your screen is glued to the keyboard. Detach it. Like in asus transformer.
The point of these displays is to (eventually) get away from slavery to the pixel. Just because a printer can render, say, 4800 dpi, doesn't mean you want to render your body copy in a 1pt text (which it can do with better letter-shape fidelity than any of my old dot-matrix impact printers); you still print at 9 or 10 points and enjoy sharper and better-defined type. Moving to high-linear-resolution screens does the same thing—you don't cram more stuff into the screen, you cram a better version of the same stuff into the screen.
Decorative visual information is still information and how much you can fit in a screen depends on it's resolution not dpi. To enjoy smoother visuals you just have to move away a bit from big screen.
