The Calendar does not allow biweekly appointments. If I want to schedule pay day for the entire year, I have to schedule a weekly appointment and go through the entire year and delete every other week. There should a feature which says "weeks" and you can choose "1, 2, 3, 4, etc."
Also, I have training occasionally that may be mon-wed 8-5. The only way to show training for the three days is to make select mon 8a through wed 5p. This does not reflect the hours of training each day from 8-5. There should be a display of smtwthfsa and you can choose which days you want a particular appointment to repeat.
Also, the reminder only allows up to 3 hours in advance then it goes to days. I actually need a 4 hour reminder due to travel time prior to the majority of my appointments. There should be an option to select hours then select a number, or days and select a number. There shouldn't be limitations.
And one more (I noticed others mentioned) is the repetition of alerts for appointments. I use the appointments sometimes as an alarm clock and need a continuous annoying noise. There should at least be an option for a continuous alert.
If these can be addressed, I think I'd be 100% happy with the droid!!!
