I hope this battery technology will materialize. We can definitely use more battery capacity as smartphones are getting bigger and more complex. By next year we will have dual core processors in smartphones. It's basically a mini computer! I find that battery technology has always lagged behind as compared to other technological advances. Look at laptops. No modern day laptops can claim 4 or 5 hrs of battery life. Netbooks can boast 6 to 8 hrs of batt life only because they use a strip down, low powered CPU (mainly single & dual core only). You're giving up CPU horse power for longer batt life.
