Just to offer another data point: The screens on many "normal"
handsets that average users have (that is, not just niche-market
"smartphones") here in Japan are at 480x800 (WVGA) pixel densities.

Another distinction that's worth pointing out: The distance at
which you observe the screen. In the case of a mobile handset,
that distance is probably between 10 and 20 centimeters. In the
case of a PC or laptop, it's likely more like half a meter at
least. In case of a TV (with a browser-enabled gaming device like
the Nintendo Wii attached), it may be something like 3 meters or so.

So the pixel density and physical size and the screen on a device
need to be considered in combination with the expected distance at
which a user is likely to be viewing the screen. In that context,
the design considerations for making content usable on a TV screen
may have a few more-than-you-might-expect things in common with
design considerations for making content usable on a mobile handset.
