The time has come for me to upgrade my phone to one that can handle what I need…

I have 23 propertys that I manage (rental). I need a phone that can keep track of basically everything from rent paid, deposits, account numbers, repairs and the like… I have T-Mobile now so I was thinking about the MDA or SDA but im not against switching. OR should I just get a PDA I can upload to my computer. Im looking for personal refferances as to what you acutally have, not what you have heard. Thanks.
