Hattori,
I don't know how familiar you are with these devices, so I'll assume you aren't and may offer more information than you are asking for. Here, goes...
Well if you really want to do it all, maybe a Palm Trio 650? This gives you one phone, and a camera and a diary. You can sync with both the PC and Laptop. Read more about it
here
IMHO, I would rather have a separate cell, palm, and camera. Usually when I am out with the camera, I don't have my PDA, or need it, and I don't take my PDA everywhere I go either (your mileage may vary). And since I got my
T|X , I rarely use my laptop anymore.
I don't know what your requirements are for a camera, but I find cameras are somewhat limited when built into phones and PDAs. I am more into photography and therefore I want to edit, crop and print nice pictures, so I'm willing to make that sacrifice. But if you just want a quick snapshot, built-in cameras do OK, but you generally can't enlarge them very much.
God bless you for having the patience to have two cell phones, I begrudgingly carry mine only because my wife any I have constantly changing schedules due to our line of work and have to closely coordinate the kids needs. When I retire, the first thing I plan to do is trade the cell phone in on a nice deep sea fishing reel

(but I'm keeping the wife

).
I keep both my work and personal schedules on my Palm, is does get crowded with entries, but I have gotten used to it for
adding calender entries and
managing my contacts . It beats the heck out of paper calendars and books (Day-Timers, etc.). And syncing between the work and home PC is painless. This actually updates all 3 machines (PC, Desktop, Palm) to have the same Schedule and Contact list. "Notes" in the Palm are "Notes" in Outlook and "To-Do's" in the Palm are "Tasks" in Outlook and they are sync?d as well.
I usually do my calendar, notes, contacts, etc. entries on my PC and sync it to the PDA. I find it easier to do because the PC keyboard is quicker (although Graffiti is easy to learn and use when you are mobile) and I can cut and paste needed info into schedule entries or separate notes which I then sync to the Palm. When I don't need the notes anymore, I simply delete them in the machine I'm using and when I sync, they get removed from the other machines, as I sync with each one. As one small example, my son has weekly tennis lessons, team practice and tournaments. When the coach releases the schedule, I simply cut/paste the email into the notes section of the team info in Outlook and sync it to the Palm. Nice and easy, and I got it everywhere. I can also
Beam this to my wife's Palm so she has it.
The Trio only has 32MB memory built in (about 23-24MB usable) so you will definitely need an additional SD/MMC memory card if you choose to go this route, especially if your Outlook calendar and contact list is pretty big like I expect it would be for your situation.
Finally, you can use
VersaMail in the Trio to read your mail. I only read my personal email account and not my company mail (at least not yet. When I leave work, I leave work, reduces stress

). I don't know how many email accounts you can set up in VersaMail, maybe someone else can chime in with some information on that. Also, I set the Palm up to leave a copy of the email on the server and delete the files I don?t want or need from the Palm. I also set the option to remove them from the mail server when I delete them in the Palm. This reduces the amount of time I spend updating Outlook on my PC and the amount of memory I use on the Palm.
Hope this helps, good luck with your decision. Let us know what you finally choose and why.
Cheers,
John
