First off, this is a great example of how a thread can allow a debate to grow without being debased to personal attacks and trolling for attention.

I'm using a Nokia
whatever with Cingular and a Palm. Into the Palm, I've loaded:
a PDF viewer (currently not loaded),
a Word viewer (also currently not loaded),
a shareware spreadsheet app (which came in very handy when buying a car a couple years ago!),
an app to log mileage (for business with various clients, medical, charity, and for different cars),
a travel directory of places to stay and dine at in various cities,
a doodling app which actually comes in very handy pretty often,
MapQuest's PDA map viewer,
a scientific calculator, and
a freeware quizzing app for studying my "language of the month".
Additionally:
I have about 300 contacts in place, each with at least a home phone, work phone, and e-mail (usually they also have notes such as spouse name, b-day, etc.); and, I DO enter the particulars from business cards directly into the Palm.
There's also the pre-loaded date book that currently has about 150 records since I haven't purged it in a while.
Finally, there's the task list I use almost every day.
Oh wait! I forgot the games I've loaded too.

Would I be able to load and use
all these applications on the
Sony Ericsson P900 you seem to be drooling over? I'd love to be able to save a bit of room in my pocket or briefcase. Memory is not an issue. I do all this on a Palm VII, which has only 2MB.
