Hi all, Jonwill is absolutely right.

A modern web browser is the key.

Maybe a way to update built in IM or create another one for google (Gtalk, hangout...), skype, facebook.

and whynot create applications for viber and whatsapp (even if a don't use whatsapp).

But once again we need a decent web browser and an updated map app (I had a pretty bad story using nokia maps in canada) so we could use the phone as main driver.
