4-5" screen... wow, that is a stretch.
Seriously, it would be nice to have a good 4" screen modern Android phone. I have to replace my Galaxy S1 phone, the iPhone4 is outdated (3G), but a good size - but people are more likely to steal it. Everything else has a 4.5~5" screen. WTF!! Make a 1280x720 screen phone that is 4"... the battery life will be better.
