I received my new Treo 680 today.

So far, pretty neat, except the phone won't work because, well, it's a long story, but I have no SIM card until tomorrow.

But I've been playing with the other features anyway. So far, so good!
I've done a lot of reading online, read a bunch of reviews before I picked this one. Mostly I just want a cell phone and Palm in one unit, don't really need the net or email on it for now. But it's nice to have it in case my needs change.
I would like suggestions on a few things.
1. What are the 2 or 3 software
enhancements that you think are most useful/important to make the Treo work better? I read in some of the reviews that the phone isn't loud enough, but I can't make a call until tomorrow so I won't know until then. The ringer is certainly loud enough! But I'm looking for suggestions like that. I'm not looking for Palm accessory software at this time - I already have and will install DateBk, HandyShop, Progect (if it works, haven't found it on a compatibility list yet) and some of my other favorites. More looking for stuff to make the phone better.
2. What are the most useful accessories? I'm planning on getting a case to protect it (I'm hard on electronics). I definitely want to play music, so I want to get a SD card, 2 or 4 gig. What helps with that?
3. What are the things you know now about your Treo 680 you wish you knew then? Please, I'm not interested in someone bashing it - I'm sure there are some dissatisfied customers out there, either with AT&T and/or with Palm/Treo. I've already read as much of that as I can find, and I think I know the shortcomings of both, as much as one can second-hand. I'll find out that stuff soon enough! But constructive ideas on how to make use of it and things to avoid.
Thanks in advance to those who participate! Looking forward to learning more about my Treo!
