So many Anonymous Cowards
To see every single comment as AC, that is unusual.
I'd post AC too but I can't be bothered. The S4 is like the iphone 5S and the Nexus 5, slightly better than their predecessors, but not really enough to make the average person care.
Sure they're all nice phones, but hold them next to what they replace and you're hard pushed to find much to care about.
We're definitely in an incremental increase phase for mobile phones at the moment.
(Not commenting on the Win Phone and Blackberries because I've not used either enough to get a proper feel for them)
