Meh...
Could care less. When I finger scroll in contacts or the all programs menus the phone works like it should.
Graphically, the VGA video must be part of what is bothering you, that takes some resources I am sure... All I see is a phone that works in the end...
P.S. Have you switched hands and done this with the Mogul on the left and the TP on the right? Unless you are ambidexterous, I can see how your left hand (assuming you are right handed) could cause lag... Just being as nit picky about your video as you are with your phone...
