“While the touchscreen is sharp and bright, it’s resistive rather than capacitive, which means instead of accurately picking up the light zap of electricity from your fingertips, it registers where two thin layers of the screen get pushed together under your finger,” Mahoney reports. “On the prototype we played with briefly, it’s much harder to get touches to register, and far less accurate than the iPhone’s capacitive screens.”
“The 5800 packs a built-in stylus for this reason—you’ll be using it a lot,” Mahoney reports. “Don’t plan on using this thing for heavy emailing or texting—you’ll probably be using T9 text entry with the touch dialpad or the stylus for most of your text entry unless you have the patience of a monk, which kind of defeats the point for an all-touch device these days.”
