I am glad you have found a combination works for you. I would dispute your definition of portable however.

The Tab is infinitely more portable than that and with no loss in functionality.

My point is that I get the same functionality from the Streak as I would from the Tab. So I can't agree with you at all.

To me, the concept here of portability is carrying one device. Each to his own of course, but what you are advocating comes outside the point of discussion on this device.
