Screen type

Screen type
Bright color screens have become the norm even for low-end PDAs, and screen resolution has become a differentiating factor: While Windows Mobile displays once laid claim to having the highest-resolution color screens (quarter-VGA, or QVGA, screens with 320-by-240-pixel resolution) --some Palm OS-powered PDAs now offer 320-by-320- or even 320-by-480-pixel resolution (compared with 160-by-160-pixel resolution on older or less expensive models).

Not all color screens are created equal: The screens on cheaper models generally aren't as crisp and sharp as those on more expensive units. That's why it's a good idea to check out the model you're considering in person before you buy.
