They have dumbed it down – Google Calendar: Get Organized Review

Google has removed some of the features I found most useful, such as being able to set an end time for tasks, set reminders, etc. I guess I will be using the Apple onboard calendar instead. I don't like it as much as I used to like the Google calendar, but now that Google has ruined it the Apple one is more useful.
