The only way to convince management types if it results in a cost saving
usually via faster development or less bugs to fix..

I think PHP4 will be supported for quite a while yet.

No.

The main advantages of PHP5.1 over PHP4 are:
1. Much improved Object Model
	* reference handling
	* access modifiers
	* interfaces
	* abstract classes/methods
	* class constants
	* static methods
2. PDO (fast db abstraction)
3. SimpleXML (easier XML)
4. Exceptions (different error handling :) )

If you don't need those, then there's not a lot of point in upgrading.

Personally, I think that the improved Object Model makes it a must have
upgrade.
