I use an iPhone rather than an iPod touch. The iPod touch is much cheaper and significantly smaller than the iPhone; it has a markedly less good screen. Several of the drawbacks you identify are mitigated in the iPhone edition (most notably, I hold my calendar on Google, synced to iCal, and by far the majority of my appointments are entered through the web interface to Google calendar).
I too used to use Palm PDAs; my last one was the amazing Sony Clie TH-55 and when I went to phone-based PDA I missed it terribly until I got an iPhone.
