There have also been some *slight* rumblings from WebIS about the possible development of a version of PocketInformant for Android. In postings in the forums there the head of the company has variously said that 1) its too expensive (in terms of man-hours vs. expected return) to develop for Android and they wouldn't be looking at it, 2) they may be looking at it, but only in conjunction with one hardware vendor, 3) they're exploring it and 4) one of key people may soon take up Android development.
I wish a more full-fledged PIM would show up soon. Most of what I really love about programs like PI (really, really good contact management with awesome category sorting and full featured searching through contacts, strong calendar functions (please, please, please can we get a feature to duplicate calendar entries), strong task management and tight integration with Outlook) I can sorta, kinda replicate on the Droid with a variety of programs (Shuffle, Power Search and Star Contacts being my stalwarts) but there's nothing like a dedicated power PIM.
