Choosing The Right Screen Size

AThe fundamental problems with screen size are power and the size of a person’s hand. Screen size is constantly growing. It is not uncommon to find screens larger than 2.5 inches these days that are capable of displaying a CIF-sized image with high clarity. At least one business handheld now boasts a four-inch screen size with 640x480 VGA resolution. This is nearly four times the resolution of a CIF image; however, it is more likely to be used with downloaded content (loaded into the handheld’s memory via a USB interface to a PC). Going beyond this, the products coming on the market now allow a user to plug an external eight-inch monitor and keyboard into the USB or Bluetooth connections on a Windows® Mobile handheld, greatly increasing the viewable image area and providing a suitable keyboard for real content creation (as opposed to that used for SMS text messages and short emails). Eventually, head-set mounted displays will most likely be available that create high-image resolution in front of the eye.
