Marty,
You're going to love having a smartphone. I resisted for years thinking all I needed was a basic phone. I was wrong, I use mine all the time. Mine is an Android, but I'm sure Apple has the same apps. I have tide and current apps that are cool, but being able to go online and check the weather radar for storms and seeing realtime buoy data is what I like most.
Oh yeah, almost forgot about the TF app....
