thank you very much for your suggestion

I do get a lot of phone calls on my tmobile phone all day long from friends and family that I usually answer so I need to keep my tmobile phone with me at all times as well (basically no difference between biz hours and personal hours)

you are right about either phone being able to handle address book and calendar but both won't be the same unless I am always synchronizing the two...a phone number that I put into my tmobile address book won't be on my verizon, etc

I would like to always have an instant-on laptop at hand but the time it takes for a laptop to power up and for me to get comfortable with it (for example in the car while parked, etc)...just to check on a note...its not worth it, I rather carry a pda for that and something like the IPhone (3.5" screen with amazing graphical user interface) or the HTC advantage (with a big bright 5" lcd) would be much easier.
