Design Patterns discussion

["Mandar Nanivadekar" <stackoverflow AT rediffmail.com>]

I was doing some more thinking on this problem yesterday.
Could it be a Bridge.
The Device pattern is an abstraction?
Some more methods could be added.
So this abstraction is varying and the implmentation may vary as well.

The device driver side of the GDI could be implemented by abstract factory.
