The battery life of touchscreen phones is nothing to do with the touchscreen tech, it's to do with the much bigger screen and better interface causing users to spend much more time actually using the phone for power-hungry functions, like having the wifi and 3G running while web browsing, using GPS, playing games, etc. Having all the Rx/Tx on, with the backlight as well just sucks power, and users want the thinnest phone, rather than a brick, so the size of the battery is limited. If I listen to 6Music on my phone, the battery is dead in three hours on 3G, 'cos it has to work harder. Batteries get better, processors get less power hungry, the next gen iPhone will be better again than the 3Gs. My old N95 would die after three hours of music playing, or a couple of hours using the GPS, so criticising the iPhone for it's battery life, when I use the thing far, far more extensively is frankly pointless.
