Activity Type Field - Do Not Use | X-Squared On Demand

The field Event.Type (which is sort of the same as Task.Type) is a difficult field to use. Here are a few reasons:

Type cannot be the controlling field for a dependent picklist.
On an Event list view (/007), even when specifying record type, the Type field cannot be edited.
Salesforce requires you to select a default value for this picklist, as well as a default value for inbound emails... yet when I bcc my Email-To-Salesforce address, the resulting tasks have no Type value.

A tweet by Andy Ognenoff of Manpower (@aognenoff) revealed another limitation: Type is not available in Custom Report Types.

That does it! I'm done with this field. Here's my solution.

Work in a sandbox (duh)
Create a picklist field on Activity (ActivityType__c).
Disable all Activity workflow rules, Chatter feeds, triggers, etc.
Using DataLoader, copy values from Type to ActivityType__c.
Using Field Level Security, hide Type from all profiles. It's just not necessary.
Edit/reactivate all your workflow, feeds, triggers, etc.
Use/adapt the code below.
Test thoroughly and deploy to production.

The Salesforce Mobile application (at least for Blackberry) defaults to a Subject "Call: (212) 555-1212" style. This will account for that. It also handles emails sent with Email-To-Salesforce, which starts the subject with "Email:"

trigger TaskTrigger on Task (before insert, before update) {
     ActivityHelper.UpdateTaskType(Trigger.new);
}

trigger TaskTrigger on Task (before insert, before update) {

ActivityHelper.UpdateTaskType(Trigger.new);

}

trigger EventTrigger on Event (before insert, before update) {
     ActivityHelper.UpdateEventType(Trigger.new);
}

trigger EventTrigger on Event (before insert, before update) {

ActivityHelper.UpdateEventType(Trigger.new);

}

This class isn't perfect, but it gets the job done. I should add try/catch statements in my test code (though I have heard recently that it's not a good idea to do so, as one may WANT the code to fail with an error if something doesn't go as expected).
