I think the PDA i.e. PIM device is going to die, phones seem better suited. It'll stop questions about 'does it sync with Outlook?' Handheld computers won't die, but people who currently buy one just to put phonenumbers and appointments into, will get their fix from a phone. Personally I wouldn't want one, don't like phones, hate mobile phones and refuse to allow them in my house. As I've said before I will never buy a machine which requires a SIM card or contract just to access a terminal or a game. I do see a future for devices which are more geared to music and video, I see Apple wanting to cash in on it too and bring their polished look and feel to it.
