Funny, I came back here looking to see if anything was new in the world of iMOnTime, only to find my most recent comment, posted in 2008 about features that I had requested that were later implemented, is now obsolete because that feature (color-coded reminders) has also been added. Very responsive! So here's a new challenge, and I'm sure I'm not the first to ask for it: get my calendar onto the iPhone.
I realize that it probably can't have the same sorts of notification features that iCal does, but just being able to view it and add entries would be very helpful. As it stands now, I have to send emails to myself so that I can add those things when I get home to my computer, and I'm SOL if I want to view my calendar without the computer in front of me. Even integration with Google Calendar would be better than nothing, since I can pull that up in the browser.
I'm still a big iMOnTime fan, and iCal's shortcomings are still painfully evident every time I give it another look, but the above situation is having me consider suffering through those shortcomings in order to gain that valuable mobility.
