If There's Any Advice You Could Give Me, This Should Be The Area - Blackberry vs. Treo?

RE/MAX agents have recently received a great offer from AT&T to get a Treo 750 or a Blackberry Curve for a fantastic price.  I'm very interested.  I have a Moto Razr V3xx that I never wanted in the first place, which is a total PILE and I hate more than anything.  So I've been kickin' the idea around. 

I like to make informed decisions.  I began by talking to people - mainly two people who I know very well and trust very much.  The first is a mortgage broker (Shawn Gerhardson - I tried to link, but it won't work!) and the other works for AT&T.

Shawn insists on the Treo.  He has Sprint, who he complains about all the time, (he does!  Read his blog!) and has had many poor experiences with them.  He began with a Blackberry, which he hated and always had problems with.  Then he switched to a Treo, which he loves.

My friend from AT&T however, has a different point of view.  She tried the Treo and wasn't impressed.  She is a Blackberry gal, and said that every associate in her store has a Blackberry.  She also said that far more Treos are returned than Blackberrys - and the Blackberrys are easier to use.

I argue that using it for personal/light business use, and living on it, depending on it, and spending most of your day using it are two different things.

So I began to make up a list of the important things I like about each one:

Blackberry

•1. Not touch-screen based

•2. Larger screen

•3. Built in GPS

•4. Comes with headset

•5. Comes with AC charger

•6. Comes with USB data cable

•7. Standby = 17 days

•8. Talk time = 4 hours

•9. Standard headphone jack

•10.          Lighter weight

•11.          Voice activated dialing

•12.          Slightly smaller

•13.          Larger processor

•14.          Trackball navigation  

Treo

•1. Can be used as a Supra key

•2. 3G Speed

•3. Talk time = 4.5 hours

•4. Standby time = 10 days

•5. 6 way calling

•6. Automatic light balance - photos

•7. Standard headphone jack

•8. Comes with car charger

•9. Comes with AC charger

•10.          Comes with stylus

•11.          Comes with headset

•12.          Comes with USB data cable

•13.          More memory

•14.          Voice command

•15.          Windows OS

So as you can see, I'm not really any further ahead than I was.  I love the idea of having a supra key, because I don't currently have one (no point in Mora, but I'm starting to move south a little further in showings...) but it isn't worth it to me if I'm going to hate the phone forever....

Can anyone help?  What do you have?  Love it or hate it?  Have you tried both?
