The Asus Eee PC offers 800x480. The Nokia 770 also > has 800x480. At this point it's hard to say what's "handheld" and what is > "screen". 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. > What we increasingly see is not a sharp distinction between > computer and mobile device but rather a continuum of computing devices of > varying sizes and capabilities. 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. --Mike -- Michael(tm) Smith http://people.w3.org/mike/ http://sideshowbarker.net/
