Screen Size: Is Bigger Better?

Last summer the HTC EVO 4G kicked off the era of jumbo-sized smartphones in style with its 4.3-inch display. Since then the trend has been big, big, and bigger when it comes to high-end handsets, with the average full-touchscreen Android phone now sporting a 4-inch screen. Some devices — the Samsung Infuse 4G comes to mind — push the envelope with 4.5-inch screens and more are on the way. Rumor has it that even the next version of the iPhone could include a screen larger than what can be found on any previous version of the hardware, much to the chagrin of Steve Jobs. Point is, manufacturers continue to move towards larger screens with higher resolutions for enhanced media experiences, though it often comes at the cost of battery life and, some would argue, portability.
