What would be a suitable Android phone for a 60+ year old businessman?
Can't go iPhone because its expensive, thus here I am with Android.
Thus I could use a few things with this phone:

1. 4" screen. Coz the other day he says the Galaxy SII too big. Me thinks anything smaller than 4" is too small for big fingers.
2. Powerful speaker, mic and speaker phone function. He has the need to speak loudly.
3. Can find accessories like cases and more importantly batteries and desktop chargers.
4. Decent enough battery life. Old N96 needs a fresh battery in by the afternoon.
5. Ease of use is a plus. Dunno if the HTC Sense UI easier to use than say Samsung's Touch Wiz or stock Android on Nexus S.

I am contemplating the Galaxy S +, but I would like to ask the sifus if there is any other good alternatives to this. Thanks for reading, btw.
