I found a Treo 600 promotion for 99.00!!
There are a number of realtors in my office that use the 600 and the 650 to open their lock boxes, which is what I am mainly interested in. I hear a lot about the 650 and how it has blue tooth, but I doubt I will ever use that. I guess my concern is there anything else that I would be missing if I don't get the 650?

FYI for the promotion you just call in 866-464-8662 and give them code number 80DBHAR0705 or say you work for HAR and you get the deal.
