Still very basic and rather non-innovative Rated 2 out of 5 stars

Unfortonately this is hardly more than what any calendar application on even the most basic mobile phone offers. There is no way to sync the calendar between the TB on different computers (similar to FF Sync) nor is there any useful way how the email and calendar component are unified, e.g. by making it possible to add "deadlines" or "reminders" for email messages or easily link a task to one or more emails or threads.
