It's really general availability for me.
In rough order of use, I'd estimate:
Shopping list
Calendar
Navigation
Using the internet to locate a nearby business while I'm out running other errands
Using the internet to check weather radar/forecast
Alarm clock
Taking snapshots that I can immediately upload rather than having to run them through my computer
Contact list/address book
DVR access (set up TV to record a program)
I have a dedicated iPod that I use for my portable music. I manage my music with iTunes, and Apple doesn't allow full integration of third party apps. There are other reasons I didn't get an iPhone, but if I did, I'd be using that for music and ditching the iPod.
I have my email accounts set up, but I rarely check email on my phone. Only if I'm expecting an email and/or I'm away from home for longer than I expected. I used my phone for both email and "entertainment" uses more before I had a tablet. Nowadays I'll bring the tablet along for trips of 1-3 days, or when I know I'm going to have an extended wait somewhere (like when I'm getting my allergy shot and have to wait to make sure I don't have a reaction).
Still, when I have a shorter wait somewhere - or when I'm a passenger - it's nice to be able to pull up TE, FB, local news, whatever I'm reading on Kindle (which syncs to the last page read - and is surprisingly readable on the little screen), or play a game. Beats the heck out of six-month-old waiting room gossip magazines (or just staring at the ceiling when I'm not in a "stocked" waiting room). And if I didn't have a tablet, I'd still be using my phone as my only computer on weekend trips.
