What apps or features makes it worth it to obsolete my working 3GS to upgrade to the $400 new 5G?
3gs is so slow.
Like dial up slow.
Im sure you have been to the app store and saw tons of apps you cant download with your 3gs.
The retina screen makes the picture HD vs SD difference.
Just put a 3gs next to a 4s and the difference is night and day.
And Siri.
They just updated SIRI to where you can ask it who won which game.
You can ask siri how many yards rushing Peterson got, or how many touchdowns aaron rodgers threw.
Very handy for people like you who are into fantasy football.
You can get a 4 for $99 bucks.
The gap between a 3gs and a 4 is much larger then the jump from a 4 to a 5.
