Are you using the Advantage as your everyday phone? (just curious

)
I have an AT&T 8525 which I am passing to my son (age 21) when I replace it with the Tilt/8925.
I have been watching the reviews/info on the Advantage and Shift with interest. I don't think I'd want to use either as an every day phone but one would be nice to have.......... (do I REALLY need to have a reason other than I like gadgets??
I do have an unlimited data plan with AT&T (so that wouldn't be an issue)
The larger screen size would be nice (duh)
Recently my home wireless was zapped by lightening (dsl modem and router got hit) so my family (4 kids) had to wait for another dsl modem to be shipped (we were able to get online via a neighbor's wireless, with their permission, and a weak signal).... but I was able to use my 8525 to connect ..... VERY frustrating to have 4 laptops and a desktop and no connection!! I wished I had an advantage then!!! (and I think my husband, who is not computer/technical savvy would have asked me to write down the details of the Advantage...and would have gone "in search of one" if I had not been able to get online through a neighbor

)
The advantage has WM...the Shift has Vista .... (I kinda prefer WM)
so.....do I "need" one????
