I feel ridiculous but I carry around all 3.

I only recently got a Blackberry 8700f. I got it mostly because I have to support other clients who are using it and to see if I could successfully integrate it with my e-mail system. So far still having problems with digital certificates on that last front.

I have been a Palm user for 10 years ever since the first Palm Pilot. I carry around my Palm TX everywhere. I love the WiFi Internet access and definitely browse the Internet with it for free using WiFi. Unfortunately there are still too many things I can do on my Palm that I can't do on my Blackberry for me to not carry around the Palm.

I have a Nokia N70 mobile phone which I also only got recently. I generally prefer just carrying around a mobile phone, rather than all 3, on short trips and when running errands and such. My mobile phone really should be just for telephoning and SMSing. However I have to admit I really like the screen, the camera, the photos and video storage and the games. Yes I admit it... the games. I play Sims on my phone for quite a long time.

The Blackberry is wonderful for e-mail and Internet access. The fact that I can work with e-mail just about anywhere is revolutionary for me. The fact that it doesn't work with WiFi however still stumps me.

Overlap: I read dozens of books on my Palm with eReader. MobiPocket on my Blackberry comes close but not 100%. I use KeySuite on my Palm for my Outlook needs and it is far superiour to the Blackberry PIM software. The Blackberry is fine for Outlook synchronisation but the calendar software lacks the functionality of KeyCalendar and the contacts software does not get all of the Outlook fields like KeyContacts does. SplashID is great on both platforms and absolutely vital for me. But I miss SplashShopper and Money on the Blackberry. Viewing photos and videos on my Palm is excellent. I find this almost impossible on the Blackberry and... here it comes... the lack of an extra memory slot on the Blackberry is a major handicap.

I don't see myself carrying just my Blackberry anytime soon. I may get to the point where it replaces my mobile phone, with slight pain, but I just can't see it replacing my Palm in its current condition.
