I'm sure the Mac version is awesome, but it's more than I want to spend for a calendar. I do use Fantastical on my iPhone and I really like it. Even though my Mac and iPhone calendars are in sync, I tend to refer to my iPhone calander more than the calendar on my Mac, so I'll stick with the stock calendar on my Macs. I'm sure the developer put much work into the new product, but it's just too expensive for my purposes.
