I have had one for several years and never explored what it fully does.
Now, I downloaded a workout training log program from sprint and it is awesome.
I used to sigh when I saw people with paper and pens loggin workouts, "because I was too lazy to do it"
but the treo is like a freakin computer on you're hip. Plus you can have mp3s on you're expandable card with bluetooth stereo headphones. Not to mention, the internet in its entirety wherever you are.
I can run my whole freakin business with this thing.
Any one else using it for other things, and please, keep the crackin one off to a minimum.
